Sex with the devil.
In hell.
Guy 1: Hey guys, guess what I did last night!
Guy 2: What?!
Guy 3: I heard he got to 666th base.
Guy 1: It was totally satanic.

Get the 666th base mug.
The act of surpassing all possible bases, with Satan watching closely to keep track.
Must be within sight of Satan, and include virgin sacrifices, bathing in goat blood, and a few occasional satanic rituals. Typically finished off by both sides fighting to the death and Satan stealing the soul of the loser.
After reaching 666th base, I'm finally a single man again. 😍
