(The blooper starts with someone talking to Little Billy (Baby Luigi) )
Guy: And that's why little fella, you can never play in the street. You might get yourself killed out-
(He is interrupted by Mario knocking the guy out with his cart)
Little Billy (Baby Luigi): The f*ck?
(Mario was listening to Macklemore & Ryan Lewis - Thrift Shop on his cart. The guy Mario knocked out with his cart landed on the floor near the shop. Mario parked his cart onto him and got off.)
Mario: Oh yeah! Let's a go!
(Five minutes earlier Mario was busy doing his own thing when Princess Peach appeared suddenly)
(Mario turns around angrily)
Mario: What is it?!
(Peach poops out a shopping list which knocks Mario on the ground. He looks at it. Peach was looking sweet)
Peach: Please buy them for me!
Mario: How about no?
Mario: Of-of course!
(More to come)
