I agree with Hayley - the tit for tat is great, but then degenerates into a free for all.
This is sadly often the case. i remembered a great scene from the film Smashing Time where Rita tushingham was involved in a messy tit for tat with a waitress. But when i looked on you tube all i could find was this disappointing scene

Carry on Films were bad at setting up good pie fights, but then spoiling then with a free for all where we don't get to see much. At least the Great Race has a lot of Natalie Wood's pied face, and 'how dare you' expressions.
However, these were AL BBS - before Bill Shipton, who came along and make our dreams of messy scenes come true.
Anyway sillysod, good clip, thanks.
