DARA O Briain is used to finding himself in hot water in his stand-up shows but a near-miss in crocodile-infested rapids left him shaken.
The funnyman and 'Mock the Week' BBC host told of the incident on the rapids of the Zambezi River in Zambia as part of a Comic Relief charity challenge.
O Briain (40) said he was close to giving up after an hour clinging to a tree stump after falling out of his raft.
The father of two and his rowing partner, Olympic athlete Phillips Idowu, lost their paddles before O Briain tumbled out. He was rescued by guides an hour later.
O Briain escaped with cuts and bruises and admitted it was a little unnerving. He "wasn't in a rush" to get back in to the water''.
The comedian urged people to donate so his scare wouldn't be for nothing.
The river charity challenge takes them along a 111km journey to the massive Victoria Falls. Organisers hope to raise £1m (€1.16m), with funds going to educate children in Zambia.
