VIDEO: Harry Connick Jr. Steals The Show On American Idol

Forget Crystal and Lee -- Harry Connick Jr. ran away with the show on American Idol this week, throwing out one-liners left and right while also genuinely helping each contestant become a little bit better.

As Idol's best mentor yet, Connick not only coached the singers, but also composed the arrangements to each song. He was the perfect fit for Frank Sinatra night, and recounted his own first meeting with Ol' Blue Eyes -- when he was upstaged by his then-girlfriend (and now wife) Jill Goodacre.

Connick was so impressive, in fact, the Internet has nominated him as a candidate to replace Simon Cowell on the judging panel next season. Connick demurred when asked about it on Ryan Seacrest's radop show Thursday:

"I don't know how good of a judge I'd be," he said. "I'm not in that world ... The pop world isn't my world. It's just not, and this is a pop show."

Should Connick join Idol full time? You be the judge:
