Are you sure you can handle 72 virgins? I mean that's a lot of punani to take care of.
May be 4 every day. All the 72 will be used within 18 days time.
Then you need to exchange your virgins with someone else, to get fresh supplies. However, I am having certain doubts regarding this. The most important of them are:
1. Is there a supply of viagra in the heaven?
2. Are the virgins free from STDs such as syphilis and HIV?
3. Are all of them over the age of 18?
The other question is: can you get a mix of virgins and not virgins, because virgins are cool and al but that's not what I prefer :-/
