Three girls agree that they are going to organize a sex party. One is supposed to find a house, second one some food and drinks, and the third one is supposted to call up some men.

After 2 days they meet and first one says: "I have found a big house with 4 bedrooms".

The second one says: "I have got so much liquor and food that we'll have enough for a month". The third one says "I've got 48 men on my list". The other two are shocked.

She starts to explain: "Well as I know guys, half of them will not show up, half of the other half will get drunk right away, and the half of the remaining quarter will not be able to get an erection. And I'm thinking that what if we want to make out twice?"
