A university lecturer was explaining the differences between various African
tribes to the next ADF observers to be sent to the UN.
"This is definitely one culture where size is everything. The Comolesi,
for example, have the longest tongue of any male in Africa. The Wambesi have
the largest testicles. The Zulu men are known to have the longest penis."
It was getting a little embarassing for some of the female officers and one
woman at the back decided she'd had enough and got up to walk out.
She had just reached the door when the lecturer called out.
"There's no hurry Commander, the next plane to Johannesburg doesn't leave
until Saturday evening".
