When Linda Lavin turns to fall backward a second time to prove Alice trusts the others, she can be seen lifting her right foot to step over the mat hidden behind the sofa to cushion her fall.
(The girls and Mel, using roll-reversal to point out the qualities that irritate each other)
Alice (in a southern accent): Hi, I'm Florence Jean Castleberry, and shoot I never did make it to the VFW dance...'cause I never did get out of the parking lot all night. Why shoot, I'd like to go out with you Bufurd, and you too J.W., and you too Bubba. It'd be a blast. What? You say you don't like to triple-date? Well, kiss my grits! (in her normal voice) Ok, now it's your turn.
Flo: All right, here goes Miss Goody Two-shoes. (in a New Jersey accent) Hi, I'm the Hackensack hotshot, and I've been to night school, rah, rah, rah. I'm the world's greatest singer. I'm the Barbra Streisand of Mel's Diner. When I back into the grill, a star is boined. I never get upset and it doesn't bother me at all that Flo has so many dates. (wrinkles her nose and twitches her mouth)
Alice: That's pretty good. OK, Vera, come on.
Vera: And heeeeere's Melvin. Ding, ding, ding, ding, ding, ding, ding. (in a rough voice) Hey! Pick up this hamburger, you dingy chick, before it dies of old age. Yeah? Stow it, stow it, stow it!
Mel: Well, heeeeere's Vera. (in a high, wimpering voice) Ooh, ooh, ooh, ooh. Don't call me a dingy chick! I'm sick, sick, sick, of being called a, a chick, chick, chick.
When this episode first aired back in 1978, Avery Schreiber was listed as one of the guest stars (as Dr. Turner) in the TV Guide listing for this episode. He did not actually appear though, and isn't listed in the guest star credits.
The title of this episode is an allusion to the 1977 movie, Close Encounters of the Third Kind. The Steven Spielberg movie starred Richard Dreyfuss and Teri Garr.
