Big Brother housemate Kris Donnelly has locked his pal Rodrigo Lopez in the stocks.

Rodrigo was a little baffled by the contraption so Kris offered to show him how they worked.

“It goes in like that,” said Kris, as he lowered Rodrigo in. “And what does this do?” asked the Brazilian. “Nothing yet. I’ll show you,” Kris replied.

Kris left Rod for a few seconds and returned with Charlie who proceeded to tickle him. They lifted his skirt over his head which upset Rodrigo.

“This I’ll be angry with,” he said.

“I thought you were going to pull my underpants down,” Rodrigo admitted after being released.

“There’s no cameras behind there!” replied Kris.
