Last night we caught up with Steve Carell at the premiere of his new movie, Date Night, in which he stars with Tina Fey, and we asked him about his worst date ever. "We went to a Jethro Tull concert," he confessed. "I was a sophomore in high school and I shook her hand good night. My brothers mocked me endlessly for that."
