I love to play basketball, but don't get to too much any more. And, for years now (like since I was a teen, 42 now), when moving throughout the house, I'll periodically pretend to do elaborate layups/dunks with an imaginary ball and slap the overhead door jamb, or I'll fake dribble around the house, breaking people's ankles, doing spin moves ending with a finger roll, or stop in front of a full length mirror and work on my step backs or free throw routine. Well, my son has started picking up on it, and he'll now run up behind me and "block" my dunk, break my ankles, steal the "ball" from me, etc. It's awesome. The wife hates it. It's even awesomer when our almost 7 y.o. daughter joins in, and yells out, "OHHH, get wrecked Daddy!!!"
