It wasn't from the movie itself. I loved the movie but for some reason I laughed hardest at a line from the fake behind the scenes stuff on the special features disc. When Robert Downey Jr.'s character Kirk Lazarus slips into a bizarre hysteria. He and a few others from the film play what he calls "Barbecue Night Tactical Grape Soda Learning Games".
Okay, I know. You're thinking, "Eric, that's not funny. I don't get it." Yep, I know. Maybe you had to be there. I mean, go rent the thing.
P.S. I'm mostly writing this post because when I searched "Barbeque Night Tactical Grape Soda Learning Games" after watching the DVD, nothing came up.
