Judge Bruno Tonioli is in the doghouse this week for his pussycat comment to Ralph Macchio & Karina Smirnoff, but he's been there before. Many times.

It's easy to pick out the times Dancing With the Stars head judge Len Goodman goes too far because, other than bad rhymes and boob comments, he's usually pretty restrained. But trying to keep up with Bruno's inappropriate comments would entail recapping at least one quote a week from the past 12 seasons of the show.

However, he has had a few "Oh, no he di'int!" moments from the past few seasons.

On the DWTS Season 7 premiere, Bruno chided Susan Lucci’s tame first dance by saying, "The Cha-Cha-Cha needs a slut." He told Pamela Anderson on Season 10, “Stripperella is back home! Do it to me, girl!” On Season 12, he leaned back on the judges' table to have sex with Kendra Wilkinson.

Tonight on the Season 12 Semifinals Results Show, we're going to see a repeat of Drew Lachey's famous "Save a Horse (Ride a Cowboy)" Freestyle with Cheryl Burke. Back on Season 2, Bruno told them, "You two can ride each other like no other!”

Lately, every Latin dance prompts him to stand up and thrust out his hips, much to Len’s embarrassment. But it's been his harsh criticism that's gotten him in the most trouble. Put simply, Bruno has no filter. So if it's good or bad it's going to come out too hard and too fast. (Sorry, couldn’t resist.)

Here are two of Bruno's most famous “inappropriate” disses.

Bruno vs. Kate Gosselin

No one was terribly impressed with Season 10 "dancer" Kate Gosselin, but Bruno didn't even attempt to be polite. He gave Kate's now infamous Week 3 "Paparazzi" Paso Doble a backhanded compliment by saying, “Actually I think there was a good thing. I think for once you played the character. You came out there, you had a look of the Superbitch from Hell. You know, the face like thunder.” Yikes.

Bruno launched his attack on Kate's Week 5 Breakfast Club Foxtrot by checking his notes for the correct wording, making it seem like a premeditated murder. Dripping with condescension, Bruno said to Kate: “Darling, I think Tony [Dovolani] could’ve had more life from a frock on a coat hanger. You were just wafting around distant, you know, catatonic. And you know, it’s just, I am actually upset because last week I thought something happened and now everything has gone back right at the beginning. And it really is not good enough. It needs a post mortem, not really a critique.”

Kate called all of the judges’ words "destructive criticism.” Tony said Bruno was “mean” and, according to him, even host Tom Bergeron thought Bruno was being "cruel."

Bruno vs. Michael Bolton

On Season 11 Week 3, Michael Bolton & Chelsie Hightower performed a painful Jive to Elvis Presley's "Hound Dog." Len said it needed a pooper scooper at the end. Bruno told Bolton, "You did it all very, very badly." He gave the Jive a “3” — the lowest score since Season 8 — calling it "The worst Jive in 11 seasons.” He and Len began to fight over who was being more cruel to Bolton.  

The singer himself was livid at Bruno for his “worst” comment and demanded a public apology. "I was disappointed with Bruno — to me, he let everybody down," Bolton told GMA. "My mom was there, she's 90, she flew down to see the show...and I just didn't expect that level of disrespect from him. Even Len stopped him and said, 'That's inappropriate.' I think he should apologize publicly and he should be reprimanded for it."

Ouch! That didn’t happen. The producers didn’t think Bruno did anything wrong, since it’s his job to be critical.

What do you think? When was Bruno most inappropriate?
