Since this is already bumped, heres a good one when youre drinking.......its quite funny.....
Call, and ask for the pharmacy. Explain that you are in a situation that needs some assistance, and want to know how much the personal lubricant is. When they tell you, say
"$4.99? Thats pretty high......Anything else I could use?" They will then name off the brands they have. Ask them their personal preference, and if its possible to test them before you buy them. When they say no, tell them that you cant afford the $4.99, and will just use motor oil, do they recommend 10w30 or 10w40?
