Kaley Cuoco had the kernel of a great story on 'Late Show' (Weeknights, 11:35PM ET on NBC), but it kind of fell apart on her. It started off great. Any time you say, "I walk in and he was a hoarder," you've got our attention.

It's interesting that the guy she was dating invited her in so casually, though, as most hoarders seem embarrassed about their home situation and tend to avoid letting people in.

Then she said she was going to tell us why it was bad to make out with a hoarder on their couch. We imagined piles falling on her, or rodents coming out of the couch, but no.

"You think things are good and things are happening," she said. But then, realizing she didn't have a great finish, she kind of sputtered out, "But you're sitting on a water bottle."

A water bottle? Was it at least filled with his urine, as David Letterman suggested while she was detailing all the things lying around?
