Andy Cohen apparently does not love Chachi.

Watch What Happens Live host Andy Cohen is always gracious and funny to all of his guests on the show, but there must have been at least one whom he didn't gel with, right? As it turns out, there is!

Andy Cohen answered viewer tweets in December 2012, and he was asked who his least-favorite WWHL guest has been over the years.

"Y'know, Scott Baio apparently doesn't like gay people and didn't like me and... so maybe Scott Baio," Andy reveals.

Whoa! We didn't realize that Andy had beef with the former teen heartthrob, but apparently he does. And that's not all Andy said about Scott.

"His wife didn't like me," Andy adds.

If you're currently asking yourself, "Who the heck is Scott Baio?," we won't blame you, as he's been on the outskirts of fame of late. His big break came in the late '70s at the tender age of 16 when he was cast on Happy Days as The Fonz's cousin, Chachi.

In 1982, Scott then landed in the Happy Days spin-off Joanie Loves Chachi, which lasted a mere 17 episodes. Apparently, America did not love the show. After that, he starred on the popular '80s sitcom Charles in Charge.

Since then, Scott has had a bit of a career resurgence of late, thanks to the VH1 reality show, Scott Baio is 45...and Single. He now stars in the Nickelodeon comedy, See Dad Run, and also played lawyer Bob Loblaw on the cult comedy series Arrested Development.

As for Andy's favorite guest? He says noncommittally while answering the viewer tweets, "Too many favorites! Every night I realize, oh my god, that person  my new favorite!" Way to be diplomatic, Andy.

However, in May 2013, he exclusively told Wetpaint Entertainment when asked about his favorite guests: "Recently, we had some great fun with boy bands! With 98 Degrees and N’Sync, those were really fun!"

So does Andy love boy bands? Yes. Does he love teen pin-ups from the late '70s? Not necessarily.
