"Wide Stance" is a reference to the long-time R senator from Idaho who was busted by a detective at the Minneapolis airport while apparently looking to have anonymous gay sex in a restroom. It seems the way guys would signal their interest to each other was by playing footsie between the stalls, and Craig's excuse was he is a 'wide guy' which somehow turned into 'wide stance'.
The Super Tuber. Most homoerotic entree I have ever imagined... you are supposed to take a potato, cut a hole through it, grease it up, then shove a hot dog through the middle.
The show Boston Legal has a bit about this. William Shatner's character is trying to take a dump and gets accused of soliciting gay sex. This is also the episode where his phone makes the Star Trek communicator whistle.
