No, really. The letter I has a flavor. I learned this at lunch today. Here's how it all went down:
M1: Mom, I know what Y would taste like.
Me: You know what 'why' would taste like??
M1: Yes. It's a letter that's not used very often, so it gets stale. So it would taste like a box of stale air.
Me: Oh. Well... right, then.
M1: And Z would taste like a box of sawdust, because it gets used the least out of all the letters. And C would be crisp, like lettuce.
M2: What about A?
M1: Applesauce, I think. Sort of sweet and sort of sour.
M2: And I know what I would taste like!
M2: ICE CREAM!!!
And now I know... I has a flavor after all.
