<human>: Alright, so my sister's pregnant, and we're going to have a baby shower in a few months or so. The baby's a boy and she's going to name him "Cash" because... y'know, Johnny Cash.

So we figured this would be a good theme to go by for the baby shower: anything that's basically money--or even Johnny Cash--related. So instead of, say, a money tree, we'd have a cash tree with fake money of the baby's ultrasound on it or something, I dunno. That sort of thing.

For the most part it's not too difficult to come up with money-themed stuff, but we have no idea what to make for party favors. So does anybody have any ideas on something cheap and relatively simple to make that follows the theme? Thanks!

Can you condense the text into three sentences or less?
