Rap It Up

Rap it Up is the name of the ninth episode in the third season of Regular Show.

Plot
Mordecai and Rigby are watching CrewCrew, a famed group of rappers, engage in rapping battles at the Park's Snack Bar. All's well until Pops shows up, mistaking CrewCrew's rapping for poetry, and shares a bit of his own. CrewCrew call Pops a loser for that, making Pops mad and challenging them to a rap battle. Mordecai and Rigby join Pops, knowing he would lose if he doesn't know how to rap.

At the house, the three try practicing how to rap, but Pops ends up quitting due to the rude nature of rapping. Everything goes downhill from there, leading to Mordecai and Rigby's abandonment of Pops to the rap battle. However, with a little bit of sage advice from Skips, the duo go to the rap battle to support Pops.

By donning Shakespearean-era clothing, the three defeat CrewCrew with poetry. Just when they thought they wouldn't be called losers, Muscle Man mocks their choice of clothing, calling them losers.
