Billy's Icy Demise

Alright, listen up, buttercup. So, Billy's enjoying his ice cream, right? Then BAM! A bus comes along and knocks him flat. The 'joke' is that the reason he dropped his ice cream isn't because he was clumsy, but because he got clobbered by public transportation. Which, let's be honest, isn't that funny if it happened to you, Einstein.
