"The Barry Gibb Talk Show" is a recurring skit on NBC-TV's "Saturday Night Live," with Jimmy Fallon playing the bipolar Barry Gibb.

In the skit, Fallon alternates between breaking out into falsetto and losing his mind on his guests if they open their mouths to talk, much less disagree with him.

On Saturday night, Justin Timberlake played Gibb's brother, the late Robin Gibb, who doesn't say much but has no problem with delivering a falsetto as needed.

Madonna made a cameo as a guest on the show, which discussed "politics," "issues of the day," "real important issues," "chest hair" and "crazy cool medallions" in this "crazy, crazy time."

Barry Effing Gibb, as he is known to call himself, went ballistic on Madonnna, who could barely keep a straight face when she made her political points. Gibb admitted that she tamed him like a wild horse as she stood up to him, because, as Robin Gibb said: "She is Madonna."

Fallon and Timberlake closed the the skit with the theme song, with the real Barry Gibb appearing and offering an assist.

Madonna and Gibb. Amazing.
