The Youngest Doctor w/ His Screwdrive

He has a bow tie as well.

ok time for a vote! the stewdriver or the sonic screwdriver? one is a plastic screwdriver that can unlock anything because no one told it it cant. the other can unlock anything using the power of sound, as well as various, though nondescript random stuff...on second thought not exactly a fair match up. sonic all the way!

Actually, that has to be one of the oldest Doctors. If you'll notice, throughout the seasons, it appears that they get younger and younger actors. Even the 10th doctor said something like "I used to act all old and important, like everyone does when they're young" So the theory is that the older the doctor gets in age, the more he regenerates, the younger his body is.

He got it from the rugrats genius.
