The exhibition industry got together at The Talk of London in Covent Garden, for ESP Recruitment and the AEO's second annual quiz and comedy evening.
Among those taking part were Reed, United Business Media, EMAP, Wembley and Marketing Event, with our imaginative team name of, er, Marketing Event.
Quiz standards were not of the highest order. Not so much university challenge as universally challenged.
But the winners, who rose above the mediocrity to win a bottle of bubbly, were BBC Haymarket aka HELraisers with a stonking score of 133.
At the other end of the scale the Nat Mags team looked like it would struggle to answer the pounds 100 question on Who Wants to be a Millionaire, coming in last with 65.
After that guests were treated to some excellent stand-up comedy before dancing the night away to the sounds of Abba and Andy Williams. Needless to say, Diary was last to leave the dance floor.
