I admit it"¦ since I've been on maternity leave this summer, I've watched The Price is Right almost every day. I did the same thing when I was in school and had my summers off, so it's kind of nostalgic. Of course, at the time, Bob Barker was ruling over his bevy of beauties, not Drew Carey. And that's not the only change that has been made over the years. Check out these 10 games that have been retired since the show's debut in 1972.

1. Bullseye. This one was nearly impossible to win, which is why it was retired. The contestant had seven chances to guess the price of a car, and after each guess, Barker would tell the contestant if he or she needed to guess higher or lower. In its five appearances on the show, Bullseye was never won.

2. Bump. This one ended up being a casualty of the infamous Bob Barker-Dian Parkinson lawsuit. The game itself was pretty innocuous - I'll let you watch for yourself below. The problem was the "wind up" the models were required to do to before the "Bump." See for yourself:

3. Double Bullseye. This was a bad game for the show - it was the only game to require two contestants, and one of them always won. This is probably why it was retired, but elements of Double Bullseye were picked up in the Clock Game, which debuted a few weeks after this one was retired.

4. Gallery Game. Perhaps trying to inject a little culture into the show, Gallery Game featured paintings of each product the contestant was playing for. Under each painting was a price tag with most of one digit missing. The contestant had to paint the correct digit in order to win.

5. Hurdles. This is a variation of Cliff Hanger, if I'm not mistaken - or maybe Cliff Hanger is a variation on this one. In Hurdles, there was an item that was used as the base price. Then the contestant was shown three pairs of products and had to guess which of the pair was priced below the base price product. As the contestant successfully guessed, a hurdler moved across the game board. A wrong guess sent the hurdler crashing to the ground. Hurdles' last appearance was in March, 1983.

6. Make Your Mark. Originally called "Barker's Markers," this may have been retired because Drew Carey flubbed the rules on a show. The contestant received $500 and was shown three prizes and four prices with the goal of picking the three correct prices for the prizes. Two correct prices were then shown, and the contestant was then faced with the decision of leaving the third price picked, or exchanging it for the one not picked at the cost of $500. Drew Carey incorrectly explained the rules and said that regardless of whether all three correct prices were chosen, the contestant would get to keep the $500. Whoops.

7. The Phone Home Game. It's shades of Who Wants to Be a Millionaire! The contestant and a home viewer would each get the chance to win some cash.

8. Professor Price. This was the shortest-lived game in Price is Right history, making just two appearances on the show. The contestant was asked random trivia questions with numbers from zero to nine contained in the answer, which was also a number in the price of a new car. Three correct responses would result in a win; three incorrect responses was a loss. In its two airings, both contestants won. But the real star of this game was the creepy, animatronic Professor Price, who reminds me a bit of Zoltar from Big:

9. The Shower Game. This one sounds ripe for a sexual harassment lawsuit, doesn't it? But no, it was pretty innocent. The contestant was shown six shower stalls which each contained the possible price of a car. Three stalls contained nothing but confetti, two contained $100 and one contained the keys to a car. If the contestant picked a confetti shower, he or she got to keep picking until either the cash or the car was won.

10. Walk of Fame. The contestant had to guess the price of some prizes but had a certain range to do so. If the contestant guessed outside of the set range, they could pick one of two autograph books. One simply contained the signatures of the PIR cast; the other contained a "Second Chance." But c'mon"¦ who wouldn't be excited to win an autograph book with the signatures of Bob Barker and his Beauties?

Any of those ring a bell for you guys? Are there any others you remember seeing back in the day that are no longer played on the current Price Is Right? As long as they keep my favorites, Plinko (of course) and Cliff Hangers, I'm happy.
