From Gene Healy:

Reader Ben notes that while Geraldo was in Iraq, some of the troops gave him what Kevin Smith fans know as "the ass hand":

Staley went on to say, "A handful of troops here wanted pictures with G and autographs. A few shook his hand. Others here wanted to harm him, were disgusted with him, thought he should have been sent home in a Humvee (a 40-hour drive south through the desert).

"We later found out a few who shook his hand had put those hands in unmentionable places prior. Army justice?"

I don't know if this is true or not, and I'm usually not a big fan of pranks, but still...this made me laugh.
