I dare Peridot to make a Slam Dunk, without any help:

Peridot: I've heard of those. It pertains to some Earth game known as Basketball.

Me: Yep. Here's a hoop *snaps fingers and a basketball hoop appears.* Now, take this ball and jump up and dunk.*gives her basketball*

Peridot: That will be easy!

(3 hours later)

Peridot: Aghhhhh!! Why?!?

Me: This is painful...

Peridot: Shut up!

Me: Make me, shorty.

Peridot: Gaah! I give up!

Me: Ugh. This is just..pointless. Next Dare!
