In Plain Sight, Season 1

Mary:
I'm sorry, but that stewardess had a bad attitude, plain and simple. I don't know how you can defend that behavior.

Marshall:
Did it ever occur to you that perhaps our flight attendant didn't appreciate being called "stewardess"?

Mary:
Yeah, well, I didn't particularly appreciate our stewardess hitting on my travel companion. Just assuming we weren't a couple. Crap! Damn it! [Raph physical therapy 3:30]

Marshall:
You must be the best girlfriend.

Marshall:
And for the record, there was no "hitting on" taking place. Just a little bit of old fashioned common courtesy.

Mary:
Really? So you think an invitation to join the mile high club is old fashioned? All right, maybe that's what passes for courtesy these days. Just not what I'd call kickin' the friendly skies old school. And by the way...if the stewardess finds the job title so objectionable, maybe he should have chosen another line of work.
