Watch where you sit!

This morning my co-worker and I traded Muni Fail stories: the 38BX never came, causing me to be late, and apparently on her 10 Townsend the driver got up and announced that yesterday two people were stuck by needles left in the seats. He warned everyone to be careful on the afternoon ride. What?!

Which makes me wonder, what's the weirdest/grossest thing you've seen/experienced on Muni seats?

I think mine's probably a puddle of urine on the 5 Fulton. Disgusting.
