Sean Lowe first showed his funny side — and won us over in the process — when he pranked Emily Maynard on The Bachelorette, pretending, to her horror, that he still lived with his parents. The prank, well, didn't quite work, as Emily sent Sean packing. Now as the Bachelor, Sean is at it again, and this time contestant Desiree was put to the test last night when Sean and the Bachelor producers played a little prank on her while at an art exhibition. Desiree was left alone with hidden cameras and a glass artwork allegedly worth $1.5 million. Watch how she reacted when the fake art fell to the floor and she was blamed in this Bachelor clip that feels more like an episode of Punk'd.
