El acertijo imposible.

Re-uploaded; the previous version had an error in the wording. Riddle: 100 people are at a party. Some shake hands. Some always lie, and others always tell the truth. At the end, each person is asked, "How many people who tell the truth have you shaken hands with?" Each person answers with a number between 0 and 99. How many people at the party tell the truth?
