If you happened to be at Lucille’s Piano Bar last Saturday night, you got more of a show that you were probably expecting.

"Family Guy" and "Ted" creator (as well as the writer-director-star behind "A Million Ways to Die in the West," but let’s choose to forget that right now) Seth MacFarlane took a break from "Ted 2" and took the stage at Lucille’s this past weekend to drink, do a little dance and perform a couple of classic songs. Several patrons captured the showman’s impromptu performance of Frank Sinatra’s "Luck Be A Lady" on video, as well as MacFarlane poking fun at the pianist for riding the struggle bus through the classic tune.

The pianist, Steve Watts, later commented on Facebook, "He called me out on it, rightfully so." According to Watts, however, he redeemed himself with MacFarlane with the rest of the one-time Academy Awards host’s setlist, including "New York, New York," "The Love Boat" theme and "an off-the-beaten-path Barry Manilow song."

Now, you’re probably thinking, "Seth MacFarlane was in Milwaukee this past weekend? Well, that’s almost as random as that one time when ‘Family Guy’ cut to a completely random, probably off-color pop culture reference joke." But there’s actually some rationale for this seemingly random celebrity sighting.

According to eyewitness accounts, MacFarlane was at Lucille's with actress Jessica Szohr and her family celebrating her mother's birthday. MacFarlane is reportedly dating the former "Gossip Girl" star – as well as the star of "Piranha 3-D," the greatest cinematic achievement in the history of the medium – who also happens to be a Menomonee Falls native. The full video shows Szohr participated in the surprise gig as well, doing a fun little dance with MacFarlane in the song's opening.

The tune's a little rough, but I think we can all agree it's better than his original ditty "We Saw Your Boobs" at the Oscars a few years back.

As much as it is a gigantic cliché to say that one has always had a passion for film, Matt Mueller has always had a passion for film. Whether it was bringing in the latest movie reviews for his first grade show-and-tell or writing film reviews for the St. Norbert College Times as a high school student, Matt is way too obsessed with movies for his own good.

When he's not writing about the latest blockbuster or talking much too glowingly about "Piranha 3D," Matt can probably be found watching literally any sport (minus cricket) or working at - get this - a local movie theater. Or watching a movie. Yeah, he's probably watching a movie.
