I get told often by people who I've just met that I look like Robin Williams though I fail to see it! (thats Robin williams of Mrs Doubtfire Fame, not that terrible singer from Take That)
I've been told from several independent sources (including complete strangers) that I look like either Sex Machine from From Dusk Till Dawn, or Bialar Crais from Farscape.
I've also got a sneaking suspicion that if I cut my hair short I'd turn into Dante Hicks from Clerks.
