King of the Hill, Season 8

Dale Gribble:
So it turns out I'm not the actual Dale Gribble, but a clone of him. The original Dale Gribble is a super-warrior from the year 2087. The second me, i.e. I, was created to help the first me fight the invading Mongol armies.

Hank Hill:
Dale, that's asinine, and here's four reasons why. First, you're not gonna clone a super-warrior out of a guy who can't even win a thumb-wrestling match. Two, you've spent your life swearing that the robots will eliminate the clones by the year 2010, so which is it, robots or clones? Three, you've already said you sympathize with the invading Mongolians of 2087, so you'd be the last one they'd send to fight them. And four, if you were from the future, you would have seen this coming.
