Idk. sometimes people aren't in the mood for jokes. ^_^
ok, so a bit of string goes into the bar with some friends, and they all find a table to chat at. she offers to go and get the drinks, so she approaches the bartender and asks, "may I get a few pints of ale?"
and the bartender responds, "sorry, but we don't serve bits of string here."
so feeling a little discriminated and slightly humiliated from such an unjustified bartender the string goes back to her table, and instead of informing her friends about the incident she messes up her hair and ties a bit of her string into a knot and then goes back to the bartender, and asks, "hey, can I get a few pints of ale for me and my friends??"
the bartender says, "s- wait, aren't you that bit of string from just before??"
and the bit of string responds, "naw, I'm a-frayed-knot."
