Most of the posters on this forum, or at least in Off-Topic, make me laugh often, that’s a nice thing to say about them. TV’s Frink, Possessed, DuracellEnergizer, Bingowings, DoubleOhFive, DoubleKO, and many more I’m forgetting.
Also, I appreciate the users who make serious discussion threads and not non-stop jokes. Darth Ender, Warbler, Trident, Killer Queen, etc.
