Get the tuna suprise mug.
When one orders a tuna suprise at a vending machine this is what happens...
1) You put your money in the machine and press the corresponding number.
2) Nothing. Nothing happens for about 90 seconds. Most people will think that the long wait is the suprise and as they are about to turn away...
3) An arm hoding a large fish appears from the vending machine and slaps you, and a voice says "Suprise bitch!"
Omar: Hey Azeem, have you tried that 'tuna suprise'?
