A Uri Geller Smeller is named after the man who claimed he could bend spoons and stop clocks just by looking at them, and is the result of a violent incident of "sitting on a mortar" after a
bad curry, when the foul miasma emanates from the
WC and works its way around the house bending spoons and stopping clocks as it goes.
Postman: "I shouldn't go to number 10 Downing
Street just yet without a
gas mask, Officer. There's been a Uri Geller Smeller incident! Give it 20 minutes if I were you."
