A classic eating contest in which a contestant tries to eat six saltine crackers in sixty seconds. No other aids are allowed (i.e. a glass of water), and the challenge ends once the last cracker(s) is/are swallowed or time runs out.
The simple-sounding task is much more difficult than than anticipated due to the dryness of the cracker.
The challenge can be made harder by increasing the required number of consumed saltines to seven or even eight for those who want to live on the edge.
Joe: I bet you cant eat six saltines in a minute.
Moe: Dude, I wreck the saltine challenge all the time!
