what do you get the man who goes commando?

Next Sunday is Father's Day. I have no idea what to get him. I could go with the normal

Satirical T-shirt
B-list movie starring Dan Akroyd
or
Coffee cup

but I honestly think those are all played out. I could go with the more traditional gifts that other daughters give their fathers, like

power tools
a remote control
a tie
socks
a lowjack

but I've never gotten him these gifts because

he hates power tools. Never uses them.
He has a wide collection of remote controls.
Never wears ties.
Rarely wears socks.
I don't even really know what a lowjack is, or if it really is an acceptabel Father's Day present.

What's a girl to do?
