I've seen some episodes allude to previous occasions where Hank apparently did pound Dale. In one I saw last week Dale was trying to escape up a ladder, and Hank climbed up after him and said, "Now I've already demonstrated I can kick your *ss standing on a ladder, so are you going to come down or am I going to have to do it again. . .?"
I saw that one!
LOL!
Dale is SUCH a weasel, too.
