Jon Stewart and Anthony Cumia had an epic swearing-match at an New York comedy club, RadarOnline.com can reveal.
And the spat was witnessed by several famous comedians including Howard Stern’s sidekick, Artie Lange.
Earlier in the evening Lange, 49, had performed at Carolines as he recovers from recent surgery for a chest infection following years of drug abuse.
Star comics Judah Freidlander, Dave Attel, Aziz Ansari, were all also at The Cellar.
