Not on in the daytime but I record "Restaurant Impossible" and watch it at lunchtime.
I love watching cooking shows as I'm eating as it makes my food taste better (no joke)...plus, that guy is so motivational, I'm ready to work again once I'm done with my lunch.
Can't stand that guy^... Gordon Ramsay, kitchen nightmares FTW.
The office on my PVR plays when I'm getting shit done. At any point you can watch for 20 seconds and laugh your ass off.
