Your wife's affair reminds me of Buddy the Elf. First other man told your wife,
"I think you're really beautiful and I feel really warm when I'm around you and my tongue swells up."
"You have such a pretty face, you should be on a Christmas card."
Other man proposed to your wife,
“First we’ll make snow angels for a two hours, then we’ll go ice skating, then we’ll eat a whole roll of Tollhouse Cookiedough as fast as we can, and then we’ll snuggle.”
"I thought maybe we could make ginger bread houses, and eat cookie dough, and go ice skating, and maybe even hold hands."
After other man reeled your wife in, your wife said,
"i love you. i love you! I LOVE YOU!"
Walking down the Upper West Side, holding hands, in public, she thought,
"I'm in love, I'm in love, and I don't care who knows it!!!"
At that point, she had reached fantasy land,
"I passed through the seven levels of the Candy Cane forest, through the sea of swirly twirly gum drops, and then I walked through the Lincoln Tunnel."
"Uh, in a magical land called new York City."
Then, you found out, confronted, and your wife discovered about the true nature of the other man, she says about other man,
"You sit on a throne of lies."
"You don't smell like Santa. You smell like beef and cheese."
You and SIL tried to get your wife to wake up and not be so naive, to see the world like it really is,
"Well, there are some things you should know. First off, you see gum on the street, leave it there. It isn't free candy."
"Second, there are, like, thirty Ray's Pizzas. They all claim to be the original. But the real one's on 11th."
"And if you see a sign that says "Peep Show", that doesn't mean that they're letting you look at the new toys before Christmas."
"By the way don't eat the yellow snow."
And your wife feeling stupid about what she has done, and full of regret (if not yet remorseful), she says to you,
"I'm sorry I ruined your lives and crammed eleven cookies into the VCR."
"I'm a cotton-headed ninny-muggins."
"Listen, some people, they just Lose sight Of what's important in life. That doesn't mean they can't find their way again, huh? Maybe all they need Is just a little Christmas spirit."
And you, thinking of this whole thing, this whole nonsensical affair, you just have to say,
"SON of a NUT-cracker!"
You want to tell off other man,
"Hey, jackweed, I get more action in a week than you've had in your entire life. I've got houses in L.A., Paris and Vail. In each one, a 70 inch plasma screen. So I suggest you wipe that stupid smile off your face before I come over there and SMACK it off! You feeling strong, my friend? Call me elf one more time."
You definitely have become "an angry elf."
"Of course you're not an elf. You're six-foot-three and had a beard since you were fifteen."
In your quiet time, thinking too much, you imagine you must feel the same as
"A tribe of asparagus children, but they're self-conscious about the way their pee smells."
