Here is Marlon Wayans celebrating his 39th birthday at Mansion nightclub on South Beach.

If you don’t see what’s wrong with the picture, look at the sentence above again. Yes, we said 39th birthday celebration. In a nightclub.

Oh, and let’s not forget his Fat Joe knock-off buddy, fully equipped with a Terror Squad chain…

Mind you, this was the exact same thing Soulja Boy was doing on Friday night… for his 21st birthday.

We want Marlon to do a little better.
