William Shatner's pants slipped down at airport security, treating dozens of onlookers to a view of the former Captain Kirk's undergarments. He had been chosen for an individual security check and was wearing baggy clothes, the San Francisco Chronicle reports. "It was awful to have people looking at me with my pants down, probably the most embarrassing thing that’s ever happened to me," Shatner said, explaining that "it was a long flight" from Los Angeles to South Africa "so I wanted to wear loose clothing, because I didn’t want anything to bind me."
