Edna And Bernie

Edna and Bernie were at the beach together on vacation. One day after coming out of the water, Bernie saw Edna reach into her bathing suit and pull out a cigarette wrapped inside of a condom. The following conversation ensued:
Bernie: What are those things?
Edna: Condoms
Bernie: What do you use them for?
Edna: Well I use them to keep my cigarettes dry while I'm swimming.
Bernie: Oh, where do you buy them at?
Edna: At the drugstore.
Bernie: What do you ask for?
Edna: Condoms
After returning home from vacation, Bernie decided to go to the drugstore. The pharmacist approached her and the following conversation ensued:
Pharmacist: Good afternoon, ma'am. Do you need some help?
Bernie: Actually, yes I do. I'm looking for some condoms.
Pharmacist: Sure, what size condoms do you need?
Bernie: Big enough to fit a camel.
