LMAO...that's awesome!
"What happened TO my preposition?
I took it ON an expedition.
Put it BY the thing I fish IN.
Got infected WITH a skin condition!"
Oh, I love that! It reminds me of a story I read in a home schooling newsletter. The mother was teaching a child grammar, and said, "The prepositional phrase is 'behind the bookcase'." A younger child walked out of the room, then came back and said, "No, it isn't! There's nothing behind the bookcase but dust-bunnies!"
