If they did, I imagine we'd be overtaken by an army of angry 7 year olds. Could you imagine? Little Johnny's birthday? the kids are allsinging "Happy Birthday". Little Donny, being the attention whore that he is, signing louder than everyone else. Then, the grand finale. Johnny exhales with all his might and as the fire is extinguished and the smoke clears, the kids dive in for the kill. But NO! Hold on! Mom jumps in just in time and explains... "Sorry Johnny, you know you can't have your cake and eat it too"... (long pause) Hit the dirt beeotch! You're about to go down!
And another thing... It's a piece of cake? (I'm referencing the expression here)
Firstly, no, it isn't. I've never heard someone say "it's a piece of cake" when referring to an actual piece of cake. Who would have to explain that to someone, anyhow? Secondly, what makes cake a symbol for simplicity? How many people do you know that can bake a cake, from scratch, without instructions? I can't. Even if you can bake a cake, it's still not easy enough to be considered the poster child for ease. Baking takes a lot more time and attention than cooking. Man, cake takes a bad rap around here.
