Company I worked at had a ping-pong table... that I only ever saw get used once, during a party. 

Like... who's that for?  If someone's out there playing ping-pong, it's going to annoy everyone around them and advertise that they aren't doing work.  And who's hanging out after work to play ping pong?  

Maybe some people used it at lunch or something.  I sure didn't.

Edit: Holy crap, a lot of people play ping-pong at work. I stand corrected :)

I was at a firestation for a few days and these firefighters were extremely aggressively competitive about foosball. Like break the table aggressive occasionally. Two real permanent tattoos got wagered over the two days I was there.
