MENSA Tests

Is anyone familiar with the MENSA intelligence tests?

I came across them when I was watching Conan O'Brien; he does a series of jokes with them just like he does "Celebrity Survey." I decided to take some myself and see how I matched up. It got pretty addicting. It's pretty fun to rack your brain to see what you know. Try to take a test here.

Here is an example:

24 H in a D = 24 hours in a day

Try some of these examples from Test #1 to see if it interests you:

3 B M (S H T R)
32 is the T in D F at which W F
3 W on a T
100 C in a D
