My kids think I'm hilarious because I always say your mom's ____ after everything they say. Usually. Okay, if truth be told, I'm the only one who thinks I'm hilarious; my kids just think I'm annoying. But if you can't annoy your kids, what's the point of motherhood, so here's how it works.
Kid: Mom this dinner's hot.
Mom: Your mom's hot.
Now you're beginning to see how this can be fun and annoying.
Kid: Mom, does this look cute?
Mom: Your mom's cute.
You can also annoy other people, like solicitors.
Solicitor: Is your mom there? (This works if you happen to sound young.)
Mom: No, she's dead. (Okay, techinically this isn't a "your mom" response; but it's still fun and annoying and only works if your mom is dead or if you're a liar.)
