Two examples:
1. Vanessa and Mike keep teasing Mandy by telling her they will pay for her Caribbean vacation. They then burst into mutual laughter.
2. Valentine's Day: Mike doesn't believe in Valentine's Day, so he doesn't usually get Vanessa a present (other than a taser). But this particular Valentine's Day, he sends her flowers--which she doesn't discover until the evening--along with a "card" that states, "Dear Vanessa: Bet you didn't see this coming. Ha! In your face. Love, Mike."
Vanessa thinks it is hilarious. And touching.
What's extra fun about Vanessa is that she loves bad puns. Mike will shake his head at the really bad ones but he actually enjoys them too. There's a delightful scene in Season 2 when Mandy comes home from a date (with Kyle). Mike is sitting up reading bathroom jokes:
What does one John say to the other? he asks her, then answers, You look flushed.He then starts laughing. Mandy gives him a patient look and shakes her head.
I don't mind Molly Cook as Mandy but I do miss Molly Ephraim. Like Jonathan Taylor Thomas, she had the ability to exactly and precisely play off Tim Allen's humor.
I do have to mention Brooklyn Nine-Nine's Kevin & Raymond--an ongoing joke in the series is that Raymond is the "funny" partner. Both husbands are so entirely dry (talk about being married to a straight man!--sorry, couldn't resist), the Scoobies are left to ponder exactly what makes him so humorous.
But hey, as long the spouses are happy, who cares?!
