A man is working at a pharmaceutical store and is
always messing up orders. His boss tells him if he screws up one
more time, he is fired.
An old man walks in and orders cough syrup. He cant find any
so he gives him a laxative instead. The man takes the laxative
and leaves the store. The boss comes up and asks why he gave the
man a laxative in place of cough syrup. He points towards the
old man who is suddenly leaning on a lightpost and says, "Look
at him -- hes afraid to cough."
