Regis Philbin explains how difficult airport security is for him given his titanium hip replacement, and Robin Williams imagines the host getting a cavity search from a TSA agent on 'Live With Regis and Kelly' (weekdays, syndicated).

Security officials usually realize who Regis is, but usually subject him to a search anyway. "It's a titanium hip and when you go through the thing, you know, at the airport, I always tell the guy, 'I've got a titanium hip!' and he's telling me, 'My mother loves you!'"

"'I don't care! We're still going to do a cavity search. Wow! I feel it!'" said Williams, channeling a security officer and mimicking an invasive search of the gloved variety.
