On the receiving end of his unexpected exposure were Mikey, Grace, Imogen, Lea, Bonnie and Richard, all lying together in two adjacent beds.
Attempting to get their attention, an excitable Shahbaz mounted Mikey's bed, jumped up and down a few times then whipped down his pants.
The housemates recoiled in horror, shielding their faces with their hands, before commenting on the frightening apparition.
"That's disgusting," Richard exclaimed. "That's the smallest penis I've ever seen! I think a fucking newborn baby is bigger."
Moments later, Shahbaz treated them to a repeat performance to prove that he was uncircumcised.
Still unimpressed, Richard told the others: "I think we're going to change his name to Shewinky."
Shahbaz refuted the "small" claims, however, insisting: "It's a grower!"
