Factual error: Al gets hired as a bartender despite having no liquor license and not having taken the course required to become a bartender.
Suggested correction: Depending on the bar all you need is a diploma or GED and be old enough per the state's laws.
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.
