The event was part of the Rotary Club of St. John's Northwest's 11th annual gala dinner and auction fundraiser at the Delta Hotel.
Former prime minister Jean Chretien, Liberal leader Dwight Ball and former premier Brian Tobin were in attendance.
Chretien took to the stage to taunt Crosbie, and joked the former lieutenant governor had better judgment when he was a Liberal.
The CBC's Rex Murphy joined in the roast, as did former prime minister Joe Clark and his wife, Maureen McTeer.
Comedian Mark Critch served double duty — he entertained the crowd in addition to hosting the event's auction.
Proceeds from the night's fundraiser will go towards the Signature Project, an affordable housing partnership between the Rotary Club of St. John's Northwest and The Salvation Army.
Monies raised on Saturday will also go to Hope Air, a charity that provides flights to low-income families requiring medical assistance, and other Rotary Community Projects.
