A name question?

Question

Why the name Anthony is equivalent to Tony and vice versa?

Answer 1

Cause Any and Thony sound really wierd.

But since we are talking names,

How do you get Bob from Robert, or Bill from William. I can't get the letter "B" to resemble "R" or "W" no matter which way I turn it. Always looks like a "B" to me.

And what about Richard. How do you get the name Dick from that. Talk about a major case of Dyslexia.
