Along similar lines (although as old as the hills):
A Tune and a Halls are sitting in a bar, having a loud argument about who is the hardest cold-relief boiled sweet.
“No,” says the Halls “I think you will find I am the ‘ardest boiled sweet you know. I am well ‘ard. I have been known to crack people’s teeth and Everythink”
“Yeah,” says the Tune “Well, I am hard because…”
And then looking around, he realises a green Locket has walked into the pub, and he disappears under the table. The Halls looks around, realises who it is and also ducks under the table.
The locket has a pint, drinks it, and leaves.
The two other guys eventually emerge from hiding.
“Hey!” he says “I thought you guys were the hardest boiled sweets known to man!…”
“Well, we may be hard” Says the Tune, “But that guy? He’s **** Menthol”
