The peace-loving twins appeared to be on the verge of an argument with each other last night, when Sam accused Amanda of screaming too much.

The pair were initially annoyed with Gerry, who had been throwing "creatures" at them earlier in the evening.

"It's 'cos of Amanda screaming," Sam said.

"Well, we wouldn't get them chucked at us, if people didn't chuck them at us," countered Amanda.

Gerry admitted that he chased the girls with spiders and moths because he liked hearing them shriek. "Just don't scream- is that difficult?" a stroppy Sam demanded of her twin.
