Due to the gang's latest "business expenses," Paddy's is in dire need of money. Frank buys a billboard to advertise the bar, but Dee decides to create a viral video to post on YouTube for promotion.

Charlie learns that The Waitress has a boyfriend and enlists Mac to find out who it is, not knowing that it is in fact Mac himself.
