Factual error: Bud goes to Marcy's bank to cash his college grant check for $25,000. She gets side tracked by Jefferson, takes the check, then gives Bud his own checkbook. Bud leaves the bank and Al and Peg come in and make a deposit on his college fund. The teller gives them a receipt showing there's $25,000 in the account. Not possible considering Marcy has the check and with a check that big, there's a wait period.
