I do not mind swearing in comedy, if there is a point to it.
I was very lucky to see Russell Peters live, in a small venue, before he got to be the big star he is today.
I am not so interested in slap stick. Sometimes I enjoy British Humour, Monty Python, etc, other times I am not in the mood for it, I find it too silly.
CBC Radio (Canada's National Broadcaster) has several comedy shows that play each week. They also broadcast on TV various comedy festivals, but I do not have a TV, so I only see those when I am away from home.
I like it when an entertainer makes me think, as well as laugh.
