This week the Charles Fudgemuffin blog takes a light-hearted look at paradoxes, starting with Swiss cheese...

1) The Swiss Cheese Paradox
Swiss cheese has lots of holes, so the 
more cheese you have, the more holes you have. However, the more holes you have, 
the less cheese you have.
So the more cheese you have, the less cheese 
you have!
2) The Arms Paradox
"If I was faced with a choice between having my arms removed and 
getting cystitis, I'd wave goodbye to my arms quite happily."
...Louise Wener
I think you might find that a bit hard, Louise.
