Regular Show 3x36 "Death Bear"

It's movie night and Mordecai, Rigby, Margaret, and Eileen are going through movies when Rigby starts talking about "Death Bear", a bear who killed his trainer in the old park zoo. Rigby dares Mordecai to have his picture taken in Death Bear's cage. He accepts, and the four head into the zoo. Rigby taunts Mordecai of being scared of Death Bear. Rigby runs into the cage, through a tunnel and screams to scare Mordecai and the girls. They take the picture, and then Death Bear comes out. They all run back to the house, where Death Bear bursts in. Eileen calls Animal Control. When Animal Control shows up, Death Bear kicks the officers around and throws them, too. Mordecai grabs a tranquilizer gun and shoots Death Bear repeatedly as he runs toward them. He tranquilizes Death Bear, and Rigby as well in the process. Death Bear is released into the wild. Margaret is impressed with Mordecai for saving her life. They hug, and Mordecai admits he was scared.
