Tough question but its easy for me. "The Older Woman" still makes me laugh out loud to this day. The show was a well oiled machine at this time in season 3. The script revolves around Jack but the rest of the ensemble each have pivotal roles and deliver the funniest lines of the entire series. When Martha comes up to meet the girls they are in shock thinking this is Jack's girlfriend. Chrissy lands some good jokes insulting her for her age. Martha leaves and Jack comes out of the shower and they tell Jack they met his girlfriend. The look on the girl's faces when Jack tells them about her surfing in a bikini is so freaking funny. But the FUNNIEST lines are from Larry, Martha, and the Ropers when Larry's seduction backfires and Martha runs out the door. When Mr Roper looks at Larry and says "You're weird" still makes me laugh out loud. When Martha asks Helen "how would you like to be seduced by a young man?" Then Helen responds "I hope you got his name and number."

This is my all time favorite episode. What is yours?

"The Older Woman" is definitely in my top ten funniest episodes. I always like the episodes where they are away from the apartment. When they go skiing , to the farm or camping, etc..

When they lock themselves in handcuffs is one of my favourites :D
