Gatorade
Gatorade was the beverage of choice for Jack Webster during NSFW's World Record Episode. Jack attempted to set a world record for drinking 64 oz of Gatorade. He came close, but spewed forth a mouthful of Gatorade in full view of the camera at the last moment, thus invalidating any hope he had of setting a record. Apparently the drinking of Gatorade was not helped by the fact that Jack had eaten McDonald's earlier.
This incident has later provoked the chat room to chant "PUKE!" whenever someone tries to drink something on camera.
This moment was included in the Thnks Fr Th NSFW tribute video.

Film Riot
In episode 48 of Film Riot, Ryan, Tim and Bruno try to see who can drink the most milk in five minutes without throwing up. It is quite reminiscent of Jack's Gatorade drinking attempt.
