Who'll Stop the Rain

Plot:

Al desperately tries to fix the house's leaking roof during the weekend of a long rainstorm. But each time Al falls off the roof, it makes Peggy and the kids wonder if he's too stupid or too cheap to call a roofer to do the job. Meanwhile, Steve lands another job at a pet store in which Marcy suffers side affects after getting bitten by a venomous guinea pig.
