A prolonged fistfight ensued, taking the two combatants all over a downtown metropolis. Peter was therefore provoked to attack him. During a flashback, the Chicken gave him a coupon, but the coupon was expired.

Peter no longer accepts coupons from any chickens after 'the incident' with Ernie. Once every season, Peter and Ernie get into a gigantic fight, that contributes nothing to the plot. Ernie the Giant Chicken first appeared in ' Da Boom'. Aside from fighting Peter, Ernie's personal life involved his wife, Nichole, who is also a giant chicken, their son, who's name has not been revealed, as well as their four eggs that have currently yet to be hatched. Overall, Ernie has no actual impact or relevance to the plot of the episodes he appears in, whatsoever, yet he still continuously appears to fight with Peter once a season anyway. Once every season, Ernie the Giant Chicken suddenly appears in the middle of an unrelated scene to get into an extensive fight with him that massively derails itself from the plot for at least 3 solid minutes, only for Peter to win in the end and return to the scene and immediately pick up where he left off, as if nothing happened. He is always getting into gigantic fights with him, but Peter always wins.

Ernie the Giant Chicken is a giant chicken who is Peter's worst enemy.
