The Beatles stars and their bandmate John Lennon were once trying to contact the dead through an Ouija board - a flat tablet featuring letters, numbers and other symbols, which ghostly spirits can supposedly control by directing a pointer to spell out words - when they thought they had made contact with the singer's mother, who had died a few years earlier.
Paul explained: "We once did an Ouija board thing when we were kids. We weren't really into all that, but somebody said, 'let's do it', so we were touching the glass saying, 'OK, nobody push it, OK?' so then, suddenly, It's moving!
"And it spells, 'congratulations... son' and we're going 'no!' and is spells 'congratulations... son...number...one...In NME'"
Realising his mother wouldn't have known what the NME - a British music magazine - was, Paul said he knew someone was cheating.
He added: "We were all, 'Oh, f**k off' and then there's George, you know, laughing - he's been pushing it all the time. Bad boy."
Although there was no divine intervention in the Ouija board, George was, however, not wrong, and The Beatles went on to have 27 UK number one hits.
