The owner asks the clerk, “What’s with that guy over
there by the wall?” The clerk says, “Well,
he came in here this morning to get something
for his cough. I couldn’t find the cough syrup,
so I gave him an entire bottle of laxative.”
The owner replies, “You idiot! You can’t treat
a cough with laxatives!” “Oh yeah?” the clerk says,
“Look at him. He’s afraid to cough!”
