I wouldn't go as far as saying he ruined my night, come on, we just beat Copenhagen 4-0!
However, I had muppets behind me today singing 'Ibrox 71', 'We all agree...' (first time I've EVER heard that), 'Who's that lying at Pittodrie' along with several racist comments today and a Davie Cooper song. That's the sort of thing that bothers me more than 1 person being a numpty an running onto the pitch.
