"The Dome Experiment"
"Birthday Gift" is the sixth episode of season seven (and one hundred eighty-seventh overall) of Regular Show. It first aired on September 3, 2015.
In spite of a bad track record, Rigby is determined to give Mordecai a great birthday gift.
It all started when Mordecai, Rigby, and Skips was on the roof fixing and replacing the tiles. Rigby makes a birthday rap for Mordecai since today is his birthday. Then Rigby goes inside the house to get Mordecai his present which was in the bathroom cabinet and it's shaped like a mug. Before he goes out, he tells himself he gives the best gifts but outside Rigby heard Mordecai telling Skips that Rigby is actually the worst for getting gifts because whenever he gets Mordecai a birthday gift, he never put any thought into them and if he does, they're usually gifts for himself but Mordecai said it's fine because he's used to it. A flashback shows a younger Rigby singing the same birthday rap but taking the gifts he gives to a younger Mordecai like donuts, a t-shirt that said "Mordecai's friend", and a birthday card with a "I.O.U. card on it". After the flashbacks, Rigby doesn't think his gifts are that bad until he opened Mordecai's gift which was a mug that said "World Greatest Rigby". Realizing Mordecai is right, he decides to get Mordecai a better birthday gift.
He goes into the kitchen to think about what Mordecai likes. Hours later he remembers that Mordecai likes videos games so he goes to the video games store but the video games cost 50 and 49 dollars.
