2 old ladies are having a smoke outside when it starts to rain. One lady says to the other, ""Do you wanna know how to keep your cigarette dry when it rains?"" The second lady responds, ""Sure"". So the first lady proceeds to tell her to buy a pack of condoms and each time she's having a smoke out in the rain, get out one of the condoms, place it over the cigarette and it will stay dry. Well the second old lady thinks it's a great idea so she strolls down to her local pharmacy to buy a pack of condoms. When she gets to the pharmacy, she asks the person behind the counter for a pack of condoms. The sales person behind the counter responds ""What size?"" The little old lady pauses and thinks for a second and then replies ""The size that fits a Camel!""
