Aaaaaabdominals

Kids comparing abs...

Cat: You didn't flex, you just sucked in your stomach.
Jack: How do you do it?
Eliza: Act like you're trying to go to the bathroom.
Cat: Like you're constipated.

Cat: You get abs by doing sit-ups and planks
(Cat demonstrates, Luke planks for 25 seconds)
Luke: I have one ab!

Luke: Hey Mom.  My belly's covering my abs.
Ben: Yep, I have that problem too.
