One time I was riding the bus home and was sitting on the side seat by the back door. Then this crazy woman, who was very large, literally jumped two feet in the air and landed on the seat next to me and half on top of me. She stared at me with a completely batshit crazy look on her face and then started singing to the tune of "Everybody Loves Somebody", keep in mind this was in the SUMMER:
"Everybody likes to celebrate Christmas! / Mary and Joseph like to celebrate Christmas! / Even Jesus likes to celebrate Christmas! / and if you don't like to celebrate Christmas! / then GO FUCK YOURSELF YOU STUPID ASSHOLE MOTHERFUCKER!"
