Zoltan (hand gesture)

During the film Dude, Where's My Car?, the two main characters, Jesse Montgomery III (Ashton Kutcher) and Chester Greenburg (Seann William Scott), run into a group of UFO cultists led by Zoltan (Hal Sparks).

[1] During the early part of the 2012 Major League Baseball season, the Pittsburgh Pirates were visiting the Atlanta Braves for a weekend series when the team was watching Dude, Where's My Car?

[2] At the time, the Pirates had endured a major North American professional sports record 19 consecutive losing seasons which, fittingly, started after the Pirates lost to the Braves at Fulton County Stadium in Atlanta in Game 7 of the 1992 National League Championship Series when Francisco Cabrera cracked a bottom-of-the-9th-inning, two-out, two-run single that scored David Justice and Sid Bream.

Over time, Pirates fans noticed the players (in particular, de facto team leader Andrew McCutchen) making the hand gesture and started doing it as well.

After a Twitter campaign to encourage the "real" Zoltan to appear at a game, Hal Sparks flew to Pittsburgh on July 25, 2012, to throw out the ceremonial first pitch, and was on hand to see the Pirates win 3-2 over the Chicago Cubs.
