Joey Chestnut gave the whole Detroit Pistons squad a front-row seat to a grub-guzzling extravaganza this week -- downing 38 chicken wings in just over three minutes -- and the players couldn't believe their eyes!!
The greatest eater of all time is slated to be the halftime entertainment when the Pistons host the Miami Heat on Tuesday ... where he'll down as many Coney dogs as he can to raise money for Forgotten Harvest, an org. that helps feed the needy.
Apparently, Jaws needed to warm up his jaws before the big moment .
