Ananova:

A US teenager has been ordered to say sorry to his home town after running across stage dressed as a giant penis during graduation.

Calvin Morett, 19, of Saratoga Springs, New York state, has to pay for an ad apologising for the stunt in his local newspaper.

Morett donned the 6ft penis costume and then ran onto the stage in the middle of the Saratoga Performing Arts Centre's graduation ceremony.

He then sprayed some of the 5,000 people in the crowd with Silly String, reports the Albany Times Union.

And he attracted global notoriety when a video of the stunt was posted on YouTube.

He was also ordered to carry out 24 hours of community service and pay £50 costs after pleading guilty to disorderly conduct.

Morett graduated from Saratoga Springs High School last year.
