Ugh. Chris Doohan's Scottish accent is even worse that James Doohan's... :P
Speaking as someone who lives in the city whose accent Mr Doohan claims to have based it on, I feel I am in a position of some authority to make such a claim.
Don't get me wrong, it's a very good impression of James Doohan, and the accent he used. But it's a homage to a bad imitation.
Gronda Gronda to all Zarking Hoopy Froods! Bowties are cool.
