There's a few I can't rewatch one of them, which was on last night, is the one where Hank find the indian arrow head and the professor from the University digs up his lawn.
I can rewatch it, but only because it's KotH, and I can rewatch pretty much any and all KotH even if it means fast forwarding through a few scenes along the way. ;) I'm totally in agreement about the arrowhead one being sub-par, though. And I can't understand why---I generally like episodes where they snark on ineffectual, hopelessly condescending academics and episodes where Hank admits to having (*gasp*) feelings for his family, even if only of the 'I'm jealous' sort. But something about this episode just didn't work, and left me with a hollow "yeah? so what?" feeling rather than the usual post-viewing "I love this show" giddiness.
On the bright side, this was followed by the one where Bobby becomes a male model for 'husky' boys' clothing, which I absolutely adore!
