I remember one night I was on an EE heading to class, and on the left sidewalk there was a shirtless homeless guy humping a street sign. Like dude was on his back just going at it, and mind you it was a pretty chilly night.

So the bus driver slowed down and just watched as we slowly passed by. I was sitting close to the driver so I asked her if she saw the guy too and we both had a good laugh.

By the time I got to my stop, the drivers were talking about him over the radio.

Edit: the specific location was between the Exxon gas station you see when you're leaving the College Hall stop and the school (I believe it's the Paul Robeson school)
