I find BS’s joke offensive to people with incontinence problems.
“Why couldn’t the bicycle get up the hill?”
“Because it was two-tyred!”
Now that’s a nice PC joke that doesn’t poke fun at anyone.
Actually Northumbiron, I find your joke offensive pal to anyone that has a medical problem and cannot ride a bike, this just shows how any statement can be manipulated by anyone that wants to cut straws.
