I'm baffled

[doodlebug]

I was driving behind another car today and I noticed that the round thing on the end of its hitch (if that's the correct term) was covered snugly by a tennis ball. Why? I mean, really, why? Why the effing hell?



Is it some sort of secret gay mating signal? Or a fashion thing?

Not sure of the reason but will profer a couple of suggestions, the hitch contains an electrical connection and the tennis ball protects that connection or simply it doesn't hurt like shit when you you bang your shin against the hitch!!!!
