We see a boy and his proud mum auditioning for a movie. In the corner of the screen we see a boy in a green shirt and he walks into the auditioning room. Then the other boy gets up from his seat, and the boy in the green shirt is back again talking to his dad.
In the Daffyd sketch, Daffyd has two nipple piercings. As those other gay men come through the door and he pushes them back, his right nipple ring has moved up his body - obviously a clip on. It stays there for a few moments, until the next shot where it's back on his nipple, with no time to put it back on.
