There are probably others (where does one begin?) But one that always cracks me up is the cartoon clip demonstrating the letter C.
The guy's favorite "C" word is "CAKE". The word appears, and he lets out a contented sigh.
There are all kinds of cakes, but his favorite is a birthday cake.
In walks Clarence, with a cake fit for a king.
"Why, thank you Clarence! And it isn't even my birthday today!"
Clarence: "I know! (Shoves the whole cake in his mouth, lit candles and all)
It's my boithday! (leaves singing) Happy boithday to me!"
And our poor hero is left there broken-hearted, and doesn't even get a crumb.
But I love the grin on Clarence's face when he lets us know "It's my boithday!" and he opens his mouth to show us his horrible jagged teeth.
I hope they include this on the upcoming Old School box set. This one's a scream!
And today is Jim Henson's boithday, so I'll save a piece of cake for him
