Watch: Michael Caine tells Jonathan Ross about the first time he smoked a joint

Michael Caine joined Sue Perkins on last night's Jonathan Ross Show to discuss, amongst other things, the first time he ever smoked a joint.

As you do.

Caine, who gave up smoking at the behest of Tony Curtis, recounted a story where he took had a bit of wacky tabacky and ended up laughing for five hours straight and almost got a hernia.

So Michael Caine's a lightweight, basically. As Caine would later explain, he couldn't smoke it primarily because he thought it would affect his memory.

Makes sense, really, but we've got images of a stoned Michael Caine wandering London, looking for an all-night kebab shop and it's just too funny.
