I was watching the big bang theory earlier, and I noticed that there’s a dartboard on the back of the front door in Leonard and Sheldon’s apartment. This is odd because I’m sure they don’t use it at all during the show, nor is there any mention of it. I quite like darts, but maybe theoretical physicists don’t tend to take it up as a hobby, even though they have the facilities available. Maybe we should thank them for not playing though, I don’t imagine Penny would appreciate a dart in the eye.
