If I ran a game store I would play the song Suds Me Up, Sulu by Warp 11.
There are very few homoerotic bath-side rock ballads suitable for playing in a game store, but Suds Me Up, Sulu is one of them. In it, Warp 11 plays their guitars gingerly trying to lure Star Trek's Mr. Sulu into a naughty bathtub encounter. The song is played for laughs with lyrics full of filthy puns. You can almost hear George Takei ejaculating his catchphrase "Oh my!" Don't worry, the song doesn't run into foul language. This one is sure to get laughter and groans from patrons in my fictional game store.
Suds Me Up, Sulu is from Warp 11's 2002 album, Red Alert.
