A game of tug-of-war:
Bruiser (with Boy Scout sock between his teeth): [pulling]
The historian, to me: Do you ever play tug-of-war with Bruiser?
Bruiser: [pulling harder]
Me: No. (incredulous)
The historian: He's very strong.
Bruiser: [uses superdog powers of pulling to cause sock-ripping tug-of-war action]
Singing son: Have you ever played chess with Bruiser? He's very astute.
Bruiser: [plots master chess strategy for putting opponent in check mate, using only his teeth]
