Hubby took the Fries up to the Mountain Roller Rink tonight, since they've been itching to go back ever since the twins were there for Brooke's birthday party.
He called me while they were on their way up there (and, yes, the rink's name does give you a good idea of the roads to get there), and related this conversation:
Medium: Oooo, it's tickling my bum!
Hubby: What is?
Medium: The hills!
Small: It's not tickling my bum.
Medium [very matter-of-factly]: Well, I'm squeezing my butt cheeks together.
