From her sly humor on Comedy Central Celebrity Roasts to her humbling takes on her own image, Pamela Anderson’s wit and intelligence are reason enough to anticipate her popping up on any talk show. So this makes it all the more surprising that she fell flat on a recent Ellen DeGeneres appearance. I’m sure as you read this, you’re coming up with better repartee than Pam managed. (“Pam Anderson falling flat? Doesn’t that violate the laws of physics?!”) In her defense, she was tired and mildly injured from a tour with magician Hans Klok, but the conversation between her and Ellen was just sporadically entertaining — mostly when Ellen herself was doing the flirting and fawning — and often confusing.

While it was intriguing to hear about Pam’s normal life as a mother (and school traffic monitor!), her low energy and bland presentation made the insights a snooze. And Ellen chatting with her like an old friend was little help, since inside talk without careful clues leaves the viewer out in the cold. To her credit, Pam got in a good line when pitching her new film “Superhero Movie” (“I loved being invisible. My wig did most of the work.”) Yet the majority of even good lines were thrown away or stepped on.

It didn’t help that Pam was positioned between Matt Grant, an engaging Brit who is the current star of The Bachelor, and Margaret Cho, both of whom demonstrated charm and perfect timing. Her 2 Whisper rating highlights some cardinal rules for talk show appearances: get plenty of rest and have your people communicate the essential ammunition the show’s producers need to make you look good, you can’t leave a great appearance to chance!
