|'LEGALLY DUMB' shirt worn by Burton Cummings (The Guess Who)|
Actually, the guy was far from being dumb. Burton Cummings was the lead singer of The Guess Who and the co-writer of one of the most famous songs ever, American Woman. Burton Cummings is also the recipient of the Order of Canada (OC) and the Order of Manitoba (OM).
If Burton Cummings can pretend to be legally dumb, anybody can.
