These Pretzels Are Making Me Thirsty

I realize we, the audience, have privileged information about each of the characters (if nothing else, we see them when the other characters don't), but you'd think that someone else on the team, other than Gibbs, would have realized the goofball is just one facet. I find it interesting that Ducky (who noticed that Tony is just like Gibbs used to be) and Abby (but then she sees a whole lot more than most anyway) are the ones who get it, rather than the trained investigators. :-)
