Mummy, who was that man?
But he doesn't quite cut it with the youngsters any more.
At a recent charity bash at St James' Park in aid of the DebRA Jonny Kennedy Memorial Appeal, Pedro was introduced to eight-year-old James Dunn from Liverpool.
James suffers from the skin disease EB, which was highlighted in an award-winning documentary about Alnwick man Jonny.
Beardo spent a lot of time chatting to James and his family, posing for pictures and signing autographs and went away happy he'd put a smile on the young lad's face.
But before Peter was even out of earshot, young James turned to his mum, looking bemused and confused, and said: "Who was he?"
Poor old Peter.
