Twitter went into a full on Britain’s Got Talent meltdown during the first night of the week of live semi-finals.

It seemed the majority of the audience back home was second screening, offering up their commentary about what they were watching on Twitter as though they were auditioning to become the next family on Gogglebox. Here’s what was going on.

Unlikely mention of Hitler

BGT presenting duo Ant and Dec asked top judge Simon Cowell about the unexploded Second World War bomb which had been found near the studios last week, triggering an evacuation.

Simon responded saying that “We’ve beaten Hitler twice” and pointing out that the show would go on.

There was a Harry Potter dance mash up

The Entity Allstars – showed us a dramatic fight scene between dancers Harry and Malfoy. All was going OK until one of the dancers, aka Harry, fell over at the end, although he reassured us he was OK.

Lots of people made witch and wizards groups – not least the judges.

Amanda Holden called Simon Cowell Voldermort
Simon responded calling Amanda a witch
David Walliams suggested Simon liked evil triumphing

The rollerbooting brothers and sisters came with a health warning

David Walliams threw some shade at Simon Cowell, aka Mr Rich

Miaow.

People couldn’t help be mesmerised by a record-breaking dog

Not everyone was convinced that Mitch and Cally The Wonderdog – who popped balloons incredibly quickly – was worthy ofthe Royal Variety Performance. That said, it was good enough to land a World Record for popping at speed. To anyone worrying about what would come up next for the act, Simon revealed there could be a “balloon-off” in the finale if the act gets through – where the daughter of the previous record holder would give it a go…

“It made me proud to be a woman,” said David Walliams

David was praising the women-inspiring Ruby Red Performers when he came out with this cracker. In the same session, Amanda joked that Alesha “got the memo” on similar outfits to the dancers – a group of older burlesque dance group from Withernsea, near Hull.

“It was very classy – and this show doesn’t normally do that”

David was on quotable form, as he complimented Becky O’Brien’s makeover from blonde hair and jeans to red-hair and red dress as “very classy”.

Space is a wonderful place – but where is Lorraine?

Simon buzzed and interrupted Lorriane Bowen but did that add to the performance of the “crazy crumble lady” or detract? You might remember that Walliams championed the eccentric singer who sang and played the keyboard on an ironing board during her first audition.

Or as this astute writer realised it’s all just made up…

Best of the rest

Amanda and Alesha buzzed during Andrew Fleming’s impressionist act, calling him dated.

Everyone liked the Welsh choir Cor Glanaethwy, even if no-one was quite sure what the Welsh singers were actually saying.

And people are getting suspicious about next year’s Eurovision entry
