A woman goes into a bar and asks for a double entendre - so the barman gave
her one.
Three pieces of string go into a bar. Before they can ask for a beer, the
bartender snaps, "Oi! We don't serve bits of string! Clear off!", so they
leave.
Later on, there's a different bartender working and they try their luck
again, but with similar results: "Sorry - I can't serve bits of string!"
They go outside again. Then one of them says, "Hey - I've got an idea!"
He reaches up and pulls apart the string at the top of his head, winding
it around itself in a bit of a mess. Then, he confidently strolls back
into the bar.
The barman clocks him, does a double take, and asks, "Ere - are you a bit
of string?"
"No", replies the piece of string, "I'm a frayed knot."
