Seagulls on laxatives

(Scroll down for video) Beach goers had an unwelcome surprise when mischievous American teenagers decided to play a prank on them.

The boys huddled over a tray of food where they were adding laxatives.

As they placed the mix on the ground, many seagulls came to snack on it.

They film the messy results as the birds start pooping on everyone within seconds.

Then the boys had a good time watching as puzzled beach goers ran for cover.
