Way, way back before 'The Hangover 3' was even a twinkle in Todd Phillips' eye, co-stars Zach Galifianakis and Ken Jeong already knew each other, and you can watch them perform stand-up together in this video unearthed from the prehistoric year of 1998.

Before he was a star, Zach Galifianakis performed stand-up comedy (and he still sometimes does), and as it turns out, so did Ken Jeong. The pair can be seen together in this video below, filmed at Petterson's Coffeehouse in Los Angeles in 1998. We had no idea that these guys even knew each other prior to 'The Hangover' series!

In the video, Galifianakis has the audience read a letter he's prepared for them, and does a little riff on an Alanis Morissette song (this is 1998 after all) before asking Ken Jeong to come up for a segment called "Everything a Greek guy wanted to know about an Asian but was too afraid to ask." It involves some stereotype humor and Jeong feigning offense with a wonderfully uncomfortable blank stare, but then Jeong gets to turn the tables on Galifianakis with a segment called, "Everything an Asian guy wanted to know about a Greek but was too afraid to ask."
