Let's get quizzical

First, and most importantly for BLS, the answer to last week's teasers...

What have the letters I, K, L, V, W, X, Y and Z all got in common?

Congrats to Tracy for this one, she spotted it straight away that they're all made of straight lines. What about A and F I hear you cry? Well a and f aren't made of straight lines.

What have the letters C, K, O, P, S, U, V, W, X and Z all got in common?

You're going to hate me. The letters look the same whether they're capitals or lower case. No, really, they are. Maybe a little smaller. Maybe slightly out of proportion. But the same.

So, to this week's brain exercise. (OK, if your brain hurt last week...)

There is a man who always tells the truth teller, a man who always lies, and one that sometimes answers truthfully and sometimes lies. Each man knows who is who. You may ask three yes or no questions to determine who is who. Each time you ask a question, it must only be directed to one of the men (of your choice). You may ask the same question more than once, but of course it will count towards your total.
What are your questions and to whom will you ask them?

hehe, get commenting.
