Since he will be out of town, Mr. Peterman wants Elaine to bid for him on a set of golf clubs owned by John F. Kennedy at an auction. He tells her he is willing to go as high as $10,000 for the clubs. Jerry thinks he hears a strange clunking noise in his car and asks Kramer and Newman, who had previously borrowed the car, about it, but they don't know anything. Newman learns that bottles and cans can be refunded for 10 cents in Michigan (as opposed to 5 cents in New York and many other states), but Kramer tells him it's impossible to gain a profit from depositing the bottles in Michigan due to the total gas, tollbooth and truck rental fees that would compile during the trip, noting his own failed attempts because he "couldn't crunch the numbers." Newman becomes obsessed with finding a way to make such a scheme work.
