Went to check out Snakes on a Plane last week - loved it .. went back in the evening with a few friends having consumed the best part of a weeks worth of green ... on the way, we stopped at a toyshop and bought 2 dozen plastic snakes of various sizes....

About half way through the movie we started (as subtley as possible) to toss them randomly around the theatre .... the reactions were hysterical .. I am sure it was the tears running down our faces which gave us away ... fortunately, everyone by one person saw the funny side ... the one who did not, was a BIG guy with his girlfriend, who had let out the most hysterical scream when a 4" plastic boa landed on his lap ....



I can strongly recommend this as a pass-time!
