Posey said he was at a church in Merritt Island, Fla., when a friend told him about the reptile under his car, Central Florida News 13 reported Monday.
"Of course I had to come out and go along with the joke, and there was really a gator under my car," Posey said Sunday. "So we're waiting for the trapper. I hope he's a gator trapper and not a squirrel trapper when he finally gets here."
The trapper arrived and was able to coax the animal out from under the lawmaker's car.
