Ha, just when I thought they'd run out of ways to continue the Dale/Nancy/Redcorn subplot, they surprise me with this. That was brilliant, and I disagree with the earlier poster---Dale can never find out, it wouldn't be funny anymore if he did. Or have as much tension--I was wondering throughout the whole deal how on Earth everyone was going to keep it from him this time.
Redcorn probably has kids with gruff voices and coughing laughs all over Arlen; wouldn't surprise me.
