My Mom lives in northern Vermont, lotsa farms and cows. Her friend has to pasture her cows across the street from her barn. So morning and night she opens the gates and herds them across. Well at night thier udders are full and ready to be milked. One evening a 'flat-lander' (tourist) had to stop and wait as the cows crossed. As the last few waddled past the front of his car he yelled out the window, "Must be hard to walk with those things between thier legs". Moms friend yelled back, "Guess you'd know that better then me".

Now if they were internal she would've had nothing to say. Is that a good reason??
