Laxative

The owner of a drug store walks in to find a guy leaning heavily against a wall...

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."

"You idiot! You can't treat a cough with laxatives!"

"Oh yeah? Look at him, he's afraid to cough!"

A doctor accidentally prescribes his patient a laxative instead of a coughing syrup

Three days later the patient comes for a check-up and the doctor asks: “Well? Are you still coughing?”

The patient replies: “No. I’m afraid to.”

I sold some baby laxative to a junkie and told him it was cocaine...

The next day he told me that was the best shit he ever had.
