I personally find a funny joke a funny joke irrelevant of the subject, recently I heard a couple of dyslexia jokes which I have told as part of the act - which have always gone down well.....   but I wonder how many people would be offended by them??

1) One dyslexic turned to the other and said "can you smell gas" - the other replied "don't be silly I can't even smell my own name!"

2) The entertainer arrived at the dyslexics club and was asked what he did "I'm a comedian" he replied. The club secretary watched him closely for a few minutes and then said "go on then......   change colour"

Now what's wrong with them???
