24 hour Pharmacy gets a call at midnight..(russian joke)

This a translation of an old russian joke that i heard as a kid, hope you like it:

A 24 hour pharmacy gets a call at midnight. The caller asks whether they have tampons in store. Yes answers the pharmacist, we have plenty of tampons. Well then shove them in your ass, says the caller and hangs up. The next day the pharmacist gets another call at midnight. Again he tells the caller that he has a lot of tampons in store. To this the caller tells him to shove all those tampons in his ass. The third night the phone rings again. Angrily the pharmacists picks up the phone. Do you have tampons? asks the caller. NO I DONT HAVE ANY TAMPONS IN STORE, yells the pharmacist in the phone. Well perhaps you shouldnt have shoved them all in your ass then says the caller and hangs up.
