Depends on what you mean by 'honorable,' I guess...

...but everytime I hear Ed Gillespie or some other Republican drone make the claim that George Bush's Honorable Discharge is some kind of proof positive that his service record was unblemished, stories like this come to mind:

"John Allen Muhammad, convicted last November for his participation in the D.C. sniper shootings, served in the Louisiana National Guard from 1978-1985, where he faced two summary courts-martial. In 1983, he was charged with striking an officer, stealing a tape measure, and going AWOL. Sentenced to seven days in the brig, he received an honorable discharge in 1985."
