Wayne Brady to play Barney's gay brother on CBS's "Mother"

Anything that has to do with the character of Barney on "How I Met Your Mother" is bound to be pretty damned funny but this may top all: on tonight's episode of the popular CBS sitcom, real-life heterosexual Wayne Brady is going to play the gay brother of raging on-screen heterosexual Barney, played by Neil Patrick Harris - a gay man in real-life.
Yes, one is also black and the other white and I have no idea if that will be explained but I get the feeling it will be pretty funny.
Here is what I know about the plot: Barney is already struggling with the fact that all of his friends have settled into the boring state of "coupledom." Then his number one wingman, his gay, black brother James, arrives on the scene. James is bacsically a gay version of Barney, always on the prowl. But he's found a guy and is settling down which further causes Barney to confont being a bachelor on his own.
Word has it that Brady could return for future guest spots. I imagine they would only make an already good show even better!
