Anybody from the UK, what does mensa mean?

that reminds me of a joke ....A bunch of mensa members went out for lunch, and soon after sitting at their table noticed that the salt shaker was full of pepper and the pepper shaker full of salt. Being the intelligent people that they were, they set out to determine how to transfer the contents of each shaker to their proper place, using only utinsels available to them at their table. When the waitress came to take their order, they reported that the salt and pepper were in the wrong shakers, but that they had a plan to rectify the problem using a napkin, a spoon and a straw. The embarrased waitress apologized, then promptly switched the caps on the salt and peper shakers. :p

hahaha..nice one, SomeGuy :D

Us hyper-intelligent pan-dimensional beings, often forget about the simple solutions lol ;)

When NASA discovered biros don't work in space they spent millions developing a pen that would write anywhere , even underwater.
The Russians on the otherhand decided it was simpler and cheaper ............................................ to use a pencil.
