BGT week 5 in pictures Added 14 May

What did the retired builder do with 20 buckets? He balanced them on his head of course. Amanda and Michael thought the 64-year-old was a pretty level-headed chap and put him through to the next round.

He's a robot from another planet, here to take over the world... but Stuart didn't only impersonate Bublé, he also took off Schwarzenegger!

Naked ambition: Britney Spears lookalike Lorna Bliss had the judges blushing with her risqué performance. It was a risk that didn't pay off as the judges pressed their buzzers... Ooops they did it again!

Nerves threatened to get the better of Jai, but a firm grip of the microphone, gave him the strength to deliver an outstanding performance!

When Dr Haze brought on his Circus of Horrors nobody knew what to expect. Once the routine got underway, nobody wanted it to stop.

No Micheal not "Watching Porn"... although it does sound similar. Bizarre, wackiness, from Thailand, perfect for the Royal Family!

Just goes to prove that size doesn't matter... look what two and a half men can do - three whole blokes, five whole blokes, a football team's worth of blokes could not move around a stage like these guys if they tried.

The sharply dressed Royal Marines proved the power of the Fourth Judge! When Amanda and Michael said no to the military drummers, the 3,000-strong Scottish crowd made their feelings known, and with a little help from Ant and Dec the judges were made to take back their nos and replace them with big fat yeses!
