Not Great Double Date - S6.E26

After the events of "1000th Chopper Flight Party", C.J. comes over to forgive Margaret for what happened then (and what happened on "Merry Christmas, Mordecai") and invites her on a double date with her and Mordecai. The trouble is, Margaret lied about havin a boyfriend so she could calm C.J. down from her rage and must keep up the masquerade with the help of Eileen and Rigby's outlandish story of how they met.
