a 7th-grade observational comic would kill with this one in home room

So I'm eating a bowl of delicious Post Grape-Nuts this morning and I'm wondering, why do they call them Grape-Nuts? They don't taste like grapes, they don't taste like nuts. Doesn't it sound like a pair of euphemisms for the same thing? I mean, why not just call them Nard-Balls?

huh-huh. huh. Thanks folks, I'll be in detention all week!
