Sometimes that's not really a bad thing...
While at KPHX...Cutter Aviation on a CT XC weekend:
Hot blonde ramp girl: So this big thing is your machine gun, right? (points to T-38 pitot boom)
Me: YES
Girl: So, like, how many knots do you have?
Me: TWO BIG ONES (seeing she doesn't get it, I say) Oh, about 600, or about a mile every six seconds
Girl: WOAH! So, uh...is that faster than just about any car can drive?
Me: Hmm...I take it you're not a mechanic here, eh?
Ok...so that last line I only said in my brain, but I was thinkin' it. Although she was dumber than a box 'o rocks, I don't think anyone cared.
And I keep going back...
