It's called the "Selective" Service... you have a number... and if you don't register they put you in jail.
No, there is no currently ACTIVE draft - but these kids know when they turn 18 they get a number too... Honestly, how else do you think the US is going to fill it's military in the coming decade when most kids think like these kids?
FYI:
Taken from the Selective Service website a minute ago:

"On October 5, 2004, the House of Representatives voted 402 - 2 to defeat H.R. 163, the bill cited as proof that the Selective Service was preparing to reinstate a military draft. The vote made official what has been a reality since January 7, 2003, when H.R. 163 was introduced despite nearly total opposition in Congress to restoring the draft. Without Congressional support, the draft cannot be reinstated. A similar bill languishes in the Senate.
Both President George W. Bush and Senator John F. Kerry have stated for the record that they oppose a draft. Defense Secretary Donald Rumsfeld also has opposed the draft on numerous occasions.
Since 1980, the Selective Service System has discharged its mission of preparing to manage a draft if and when Congress and the President so direct. The House action proves that the Selective Service has gotten no such direction. That being the case, the Agency will maintain its readiness as required by law, and to register young men between the ages of 18 and 25. That mission has been reaffirmed frequently by successive Administrations and by Congress under the leadership of both parties."
