Did they all kiss Beaver? (I don't recall Mrs. Tompkins.)

They all kissed Beaver. Correct.

Miss Tompkins was the wallet lady who kissed Beaver and promised to send him a nice present. . I almost forgot her. I did forget Mrs. Hathaway who was Aunt Martha’s friend in Visiting Aunts.

Also Vickie from The Dramatic Club, although we didn't witness it.

Ah, yes, Miss Tompkins, or, as Beaver called her, "lady" (I never liked that moniker, and he used it with any grown female he didn't know).

And, he escaped getting kissed by Linda and her friends at the all-girl birthday party, when he ran out of the room.

Wally didn’t escape Marlene when she cornered him in the car and put the moves on him. He sounded like Gomer Pyle..... Golllllly.

Wally told Beaver he was playing in the pony leagues and Mary Margaret was batting in the World Series.

Beaver could have said the same about Marlene compared to Wally. Marlene makes Julie look like Rebecca of Sunnybrook Farm.

Didn't Gilbert describe Marlene as "A woman of the world."?

Marlene was a “woman of the world.” Love how Beaver is like a prosecuting attorney questioning her about her whereabouts last Saturday and calling her Miss Holmes. I’m surprised Marlene didn’t ask Wally “What’s up with that brother of yours?” I think Ward liked her!
