Funny Joke

Two guys are chatting at the bar.
"So, how was your holiday in Africa?" asks one.
"Don't remind me," says the other, "I very nearly got myself killed!"
"Go on, what happened?" he asks.
"Well, I was hiking in the savannah when a lion appeared out of the blue and started chasing me. I ran for my life, but the lion kept getting closer and then just as it was about to pounce for the kill it suddenly slipped and broke its leg."
"Jesus Christ, I would have shit myself!" he replies. ......"What the fuck do you think the lion slipped on?"
