Please pass the cold comedy

Dinner conversation at our house:

Lucy belches over our cracker-encrusted cod and giggles.

"My burp," Margaret announces.

Lucy's head whips up. "No! My burp!" she corrects.

"No, my burp," Margaret cheerfully disagrees.

"NO! My burp!" Lucy insists, a little outraged.

"NO! MY BURP!" Margaret shouts.

"Noooooo! MY BURP!" Lucy cries.

"No. No. My. Burp." Margaret crows.

"MYYYY BURRRP, MargaRET!" Lucy screeches, tears forming.

"MYYYY BURRRRRRRP!" Margaret yells back.

"Mommmmy!" Lucy wails.

"Lulu! Why do you listen to her? She's 2 years old and she's crazy!"

"Weeeelll," she sniffs.

Recovering, Lucy shouts back, "You are not invited to my birthday party!"
