Need a hand with a certain episode...

[Superstition]

Peggy tells Al she ordered him a pizza, the doorbell rings and Al runs to the door. It's Marcy, and Al says "It's flat and cheesy but it's no pizza..."

Which season and episode is this? It's racking my brain! I have went through all 8 seasons on DVD and have not been able to find it.

Thanks so much.
