'Watch What Happens: Live' with Jillian Michaels and Melissa Rauch

On last night's episode of "Watch What Happens: Live," energetic host, Andy Cohen welcomed fitness guru from "The Biggest Loser," and from "The Big Bang Theory," Melissa Rauch, who plays the wife of mama's boy, Howard and his bartender of the day was author and producer, Jack Gray with his new book, "Pigeon in a Crosswalk."

A pre-Valentine's Day episode, Andy mentioned that he was intimidated by Jillian, but because Jillian was there, he promised his audience to do a pushup with Melissa on his back, for each "Word of the Day," said during the show. The secret word was "dog" and if not familiar with the show; the adult audience is supposed to take a drink each time the word is said during the show.

The first game played was "Big Bang or No Thang-ks!?" Melissa and Jillian (who is gay) were shown a picture of a famous nerdy person, and they had to vote if they would or would not be with them. First up was Albert Einstein, Melissa said no, she said yes to Mark Zuckerberg, Jillian said no to Thelma from Scooby-Doo, Melissa said not to Bill Gates, Jillian said no to Rachel Maddow, and Melissa told her to jump on that, Ben Stein's picture came up and got a thumbs down, but Jillian said yes to Condoleezza Rice, Melissa said no to Urkel and when Woody Allen's picture was flashed and Melissa said yes, Jillian gave her a look like she does on the show when people do not want to exercise.

Melissa is a super fan of all the housewives, and one was on the phone. Her voice was disguised. Melissa tried to guess, but she further tried to mislead Melissa. It was Brandi Glanville, who they congratulated on her new book.

Questions from the viewers asked; Jillian if she was still in touch with Jackie Warner, her ex-business partner and what their relationship was now; Jillian said they have not seen each other in ages, but she hopes all is well with her. Another viewer wanted Melissa to do Howard's mother's voice, which she did perfectly. A viewer wanted to know from Jillian what was the best way to work out in order to get a smaller stomach; besides watching what you eat, Jillian said high-intensity exercise is the key. Andy asked if sit ups were important, and she said absolutely not, it is multiple-muscle training. Another viewer asked who was the funniest person on the set of "Big Bang Theory; Melissa replied after much thought that it was Simon. A viewer asked Melissa, who her favorite housewife was; being a Jersey girl, she replied Caroline Manzo. Actually, Melissa was to appear at the Halloween show as Caroline, but Hurricane Sandy curtailed that, but they showed a picture of her dressed as Caroline.

As a clubhouse first, they had a segment called "The Real Housedogs of the Clubhouse." They had three shelter dogs dressed in costumes and the one who won was dressed as Teresa Giudice. They noted that all dogs were up for adoption at Bidawee and encouraged fans to adopt shelter dogs.

A text poll asked who was the favorite Bravo dog? The choices were; Coconut, Cookie, Giggy, Jackpot and Playa. The winner was Giggy.

They said the word dog 21 times and Andy did all those pushups with Melissa on his back as the show closed. Good job, Andy, fans love you and "Watch What Happens: Live."
