Midnight?

A drunken fellow was in a pumpkin field having sex with a pumpkin that he had just drilled a fresh hole into.

Apparently, he was having a very good time until one of the local police cars drove up. It was an awkward situation for the female officer, but she felt compelled to ask the man, "Excuse me sir, but why are you having sex with a pumpkin?"

Somewhat shocked and confused, the man looked at the pumpkin and asked, "Damn,.... is it midnight already???"
