LOL! From Janet Charlton (via Towleroad):
"Vinny Gaudagnino and The Situation returned to their Jersey Shore SUV to find that someone had taped a sign on the back that said 'Gay Men On Board.' They look flabbergasted, but they’re not laughing. Who did it? They removed the sign but Jenni thought it was funny and when they weren’t looking she put it back on."
