Because you can't just throw a convention these days without two rival nerd gangs going at it, a group of Doctor Who and Star Wars fans at the Norwich Sci-Fi and Film Convention got into a heated argument about something that's probably just going to make us all sad.
Both sides admitted there had been a long-running rivalry between the Norwich Sci Fi Club and the Norwich Star Wars Club.
The dispute erupted after the treasurer of Norwich Sci Fi Club, Jim Poole, arrived at the event hosted by the rival club at the University of East Anglia.
He was asked to leave as he approached Doctor Who actor Graham Cole for an autograph - leading to a stand-off which was only resolved by police and university security.
A spokesman said: 'After lengthy investigation, talking to witnesses and reviewing good CCTV footage, it was confirmed that there was no assault.
'The two rival groups were spoken to and advised to keep out of each other's way.'
Well that was depressing. But seriously, who do you think would win in a fight -- a Star Wars fans or a Doctor Who fan? My money's on any bystander who just feels like throwing a punch.
Thanks to CMW and Mike C, who allegedly know a guy who got shanked with his own sonic screwdriver for calling Jabba a fat shit.
