Frogs are such ridiculous animals that everything about them is fodder for jokes or parodies. Frogs have been used in comedy for so long that you have to smile just looking at one!
1. Kissing a Frog
They say you've got to kiss a lot of frogs before you find a prince. The fairy tale The Frog Prince has the moral of not judging someone by their looks. The story of Beauty and the Beast would have been a sufficient tale for this concept, except for the fact that some women think horrible beasts are sexy. A frog? Not so much. The whole idea of kissing a frog is funny, but its also so easy to twist this tale into something you wouldn't expect.
The amazing leaps frogs do has been studied by scientists and recreated in robotic form. It also lead to a pointless but funny-looking game that recently got the mayor of Belfast into a bit of trouble when he injured a tomato playing leap frog.
More frog funniness, after the jump.
Yes, they taste like chicken. The back legs are the only part of a frog that has enough meat to make cooking worthwhile. Cutting them away from the rest of the frog doesn't make them stop jumping, oh no! My mother cooked frog legs exactly once, and was so disgusted with chasing them all over the kitchen to put them back into the frying pan, that she forbade my dad from ever bringing more home. But the rest of the frog? Not edible. That's why you'll so often see cartoons about amputee frogs. A Google Image Search for "frog wheelchair" will yield a treasure of such comics.
4. Eating Flies
Time's fun when you're having flies! A frog's tongue can move so far and so swiftly, the fly will never know what hit him. If you've ever seen it happen, you have to laugh. Add the unexpected and you have comedy gold.
The way frogs sound is funny. The usual frog croak is often translated as "ribbit", although the folks at Budweiser would disagree. A person with a hoarse or scratchy voice is said to have "a frog in the throat", which can scare literal-thinking children. The character Froggy from Our Gang got his nickname from his rough voice. When someone dies, we say he has "croaked". And some frogs can even scream!
I know what you're thinking -that's toads! But according to Wikipedia, there is no taxonomic reason for distinguishing frogs and toads. Toads are basically frogs who live on dry land. Some species of toads and frogs have parotoid glands which give the appearance of warts, but are not warts and are not contagious. They are, however, toxic. Dogs can get into trouble by catching a toad because the parotoid glands will exude poison. There have been stories for decades about people who lick toads in order to get high, but since proof or participants are as rare as hen's teeth, this is pretty much an urban legend.
7. Kermit the Frog
Jim Henson's favorite puppet that was his on-camera alter ego evolved into Kermit the Frog. Kermit became the star of ads, TV shows, and movies, but never let it go to his head. In fact, Kermit always had a melancholy self-effacing outlook. After all, it's not easy being green.
