Mrs. Foreman gives Hyde and Eric"snack-paks" from her bag of groceries. "Here, go have a snack pak." However, she hands them the snack paks we know today - the ones in the see-through plastic containers with peel-off lids. In the 70s, snack-paks only came as little pop-top cans, like Fancy Feast cat food.
Actually, she gives the snack packs to Hyde and Fez. This was after Hyde was caught trying to steal the beer from the fridge and Fez was supposed to act as a look-out but did not. Just wanted to clear that up. :-)
