All's Fair in Oven War/Gags

Couch gag
The couch is outside, mounted on the end of a catapult. The family sits on the couch, and then get launched skyward (Maggie be-ing the only one who enjoys the ride). Maggie and Bart are unharmed, Lisa seems to feel even better. Marge has a minor injury and Homer yells "D'oh" as he suffers the most serious injuries.
