A pretty typical conversation at dinner:

Erin: Xander, your muscles got very strong today!
Xander: I'm strong!  So Strong!! (shows muscles by raising arms above head)
Jake: When you are big, are you going to be stong like Daddy?
Erin: and Mommy....
Jake: and Mommy....
Erin: Xander, who do you think is faster, Mom or Dad?
Xander: Daddy!
Jake (trying to make up for the previous miss): I don't know Xander, Mommy is pretty fast!
Erin: Xander, who do you think is stronger, Mom or Dad?
Xander: Daddy!
Erin: but Xander, who do you think has the greater strength of will?
...
pause
...
Xander: Xander!!!!

Yep.  He know's exactly what's going on around here!
