Did you ever notice that the words "towel" and "bowel" rhyme? I mean, you probably knew it but never thought about it.
Anyway, so that can be confusing when your friend comes to you and says, "I was at the beach the other day, and this guy's bowels were all over the sand."
Then you'd be like, "Ewww." But then you'd realize he probably said towels and not bowels, so you say, "Wow, that's not cool that he was taking up so much space with his towels."
Then your friend says, "No, I said bowels. It was really gross."
Then you say, "Ewww."
