50 Cent once referred to Eminem as his "favorite whiteboy," and it's only fitting that Slim Shady celebrated 50's birthday in style. 50 Cent shared a video on his Instagram in which Eminem delivers some birthday wishes, along with his own rendition of the 50 verse that made him "want to quit rapping." 

The verse in question is verse two of "Places To Go," an Em-produced cut found on the 8 Mile OST. Em delivers his best 50 impression, and ends the video with some heartfelt birthday love. Check out the video below, and sound off on your favorite 50 / Em collab (that isn't named "Patiently Waiting").
