(this takes place in the 'old west')
these two bank robbers are running away after a heist, so they jump on a wagon and take off. The one says to the other "keep your eye out for anyone following us"... about five minutes pass, "do you see anything?" ... "well yeah!"... "what is it???"... "i dunno, boss, it's only about an inch tall" (as he holds up his hand and measures an inch with his fingers)... "well keep your eye on it and tell me if it gets any bigger"
another five minutes pass... "do you still see it?"... "yeah, it's much bigger now.. it's just about three feet tall!!"... "well, what is it???"... "it's an injin!!!"... "ok, just keep your eye on him!"
another five minutes pass... "is he still behind us?"... "yeah, he's climbing on the back of the wagon!!!"... "well shoot him, shoot him!!!"... "i CAN'T, i've known him since he was this big!!!" (measures an inch with his fingers)
hehehehe!!!
