Meeting a fellow RPer while grinding on a quest in WoW.
Leaving so I could spend two hours driving around randomly with my friends, from leaving a paper about chinchilla care on a friend's exes car (mostly for confusion, little malice), to ending up at a Meijer, which none of us realized reached this far north. In addition, we were lost most of the time.
Playing a PvP match in World of Warcraft, and on our final run for the flag, I start singing "Bohemian Rhapsody" over chat.
Other players join in, and it is our battle cry.
A pair of people playing Bocci. At 00:30 next to Main Street.
