I know he won't learn it until he's MUCH older, but LB really needs to learn some sarcasm, his parents will appreciate it:

How the conversation actually went:

LB walks into the house from the front yard, holding his crotch.

Dad: Do you need to go potty?
LB: Yes

How the conversation SHOULD have gone (in my little twisted corner of the world):

Dad: Do you need to go potty?
LB: No, I'm auditioning to be the next Michael Jackson!!
