John decides to take up an offer of optional life insurance that promises a large payoff, and then finds out he must have a colonoscopy -- which first requires an enema.

DiResta is put in charge of supervising a young graffiti artist while he scrubs his work from the subway, but the kid's father doesn't show up to get him and John ends up baby-sitting.

The DiRestas offer to host Tully and Amanda's wedding, but the bride's family is rather snooty; meanwhile, John finds a dead transit cop---under his kitchen sink.
