Sex. (With which he rolls in our whole relationship so no worries that I'm getting skipped over in this deal.)
Guns. "I couldn't live without my guns." It's true. There might need to be a 12-step program formed if he ever has to give them up... Well never mind. He'd move to Alaska or Canada or Siberia before he gave up his guns.
Pizza. It's been months since we've had any pizza and it's no wonder it made the top three out of the old "absence makes the heart grow fonder" phenomenon.
For what it's worth, I suspect that the Mustang he's planning to buy soon will quickly overtake pizza in the third position when pizza is no longer on the no-fly list.
I also suspect that numbers 1 & 2 are locked in for life.
Note: CPIL - your favorite son in-law apologizes if his mentioning guns on the list offends you. Ha ha. :-)
