Before Prince William's 21st birthday on June 21, Aaron Barschak was just another entertainer trying to get a break.

But by crashing the royal bash at Windsor Castle, dressed as Osama bin Laden in a pink dress, Barschak started the clock ticking on his 15 minutes of fame. He was also arrested for trespassing but never charged.

Well, on Wednesday, reports the BBC, Barschak, 37, who describes himself as a "comedy terrorist," was back in his game, trying to crash into Scotland's Edinburgh Castle in his pink Osama dress and fake beard. And this time, he wasn't alone.

Accompanying Barschak, who is just about to open his own comedy show -- "Osama Likes It Hot" -- at the Edinburgh Fringe Festival, were fans wearing masks of Prince William, Prince Charles, Camilla Parker Bowles and Queen Elizabeth, reports the BBC, which says Barschak's intention was to hold a press conference inside the castle grounds.

Only this time, he didn't make it past the gate. Furthermore, journalists were not pleased to find him pulling another stunt.

After a testy exchange with one, says the BBC, Barschak responded: "I'm not funny. I'm talentless as you can see. In fact, I'm so talentless, I should have your job."
