It's interesting that in a forum devoted primarily to Whitney and other mountaineering issues that one thread has proven to be so popular -- "Where Are the Silly Jokes".
We all clearly like to laugh.
And there is good evidence from many posts that we all like to think. There are clearly folks amongst us that can claim to being more than half wits. Even Wagga! :-)
I wonder if a new thread as started here might be popular?
Here's an initial puzzle:
All plods are also plops.
Half the plops are also ploms.
Half the plods are also ploms.
Half the plops are also plods.
There are twice as many plops as either ploms or plods.
There are two plods that are also plops.
How many pure plops are there?
