Ok, complete this; A man drops his spoon in a restraunt and the waitor gives him a new one fast, the man says 'howd u do that so fast' the waitor says 'we use string to makeit quicker to get people spoons instead of going to the kitchen' the man smiles and starts to eat then look down he says 'whats that'. Complete the joke
The wrong dish or an empty dish because the food fell off when it was going on a string. Or a spider.
Clue: The man looks down and says 'whats that' the waitor says 'its how we go to the toilet fast' what comes next
