An old multi-billionaire is lying on his deathbed... And he calls his 3 best friends into the room.   ""Now look,"" he says, ""I know I won't be alive much longer, and you know I love my money. I want to prove to my family that you CAN take it with you when you go. So, to keep them from getting their greedy mitts on my money, I'm giving each of you one billion dollars of my money to keep in trust until my funeral, at which time you will place the money in my casket before they close it.""   His three friends agree, and they each leave with one billion dollars.   Three weeks later, the old man is dead, and the three friends show up at the cemetery for the funeral. The first friend, a dentist, stepped forward, dragging a suitcase full of money.   ""I have a confession to make. I...used $10,000 of the money to get better equipment for my office, and $3000 more to fix all of my family's teeth.""   The second friend, a surgeon, stepped forward with his suitcase in tow. ""I too, have a confession to make."" he said. ""I used $50,000 to fund my clinic, and another $10,000 to give my wife the cosmetic surgeries she has always wanted.""   The third man, a lawyer, simply stands there, growing more and more red in the face with anger. ""YOU UNTRUSTWORTHY BASTARDS!"" he yelled.   ""I WROTE HIM A CHECK FOR THE FULL AMOUNT!""
