Mom: So, I found this really cute shirt for Ben. It says, "Got Grass?" on the front and the bluegrass festival's name we're at on the back.

Mom: You know, like the "Got Milk" ads, but for bluegrass. And I guess it could stand for marijuana.
Me: Yeah....I don't think Ben's that much into bluegrass. Or pot, for that matter.
Mom: I know, but it was different and I thought he would like it.
Me: Mmmm.
Mom: Well, anyway, this store had those t-shirts and a lot of other really neat clothing. They had BEAUTIFUL dresses that were tie-died such pretty colors...[conversation continues]

Right. You can imagine how successful our joint shopping trips are, can't you?
