A man celebrating his buck's day with 26 of his mates thought it would be funny to strip off and be first past the post at the Moruya racetrack.
Problem was a race involving real horses was tearing down the home straight when the streaker made his mad dash.

From news.com.au:
Jockey Tracy O'Hara was almost sent crashing to the turf when her horse Morcombe took fright as the streaker staggered on to track south of Batemans Bay during the last race on Saturday.

O'Hara and her horse were well clear of their rivals 100m from home only to slam into the inside running rail when the bleary-eyed intruder entered the course.

O'Hara was "upset and annoyed'' by the streaker's foolish antics.

Rival horse Bournda See stormed home to finish first past the post.

Racing NSW stewards, however, were forced to scrap the race because of the interference which angered punters and owners keen to win some cash.

Steward Craig Yeo could not recall a previous time when a streaker stopped a race.

A 31-year-old man from the ACT was arrested at the track and later issued with a court attendance notice for offensive conduct. He will face Batemans Bay Local Court on March 17.

Police also expect to charge the man with entering enclosed lands.

But the situation only got worse for the man and his mates when they returned to town that night, only to be told they were no longer welcome.

Waterfront Hotel owner Greg Hargraves said the intoxicated punters were already starting to blither when they checked in.
