This is what my dad said the other day while shopping for mothers day presents with my mom...
Mom: We have to get our moms mother's day presents while we're here.
Dad: How many is that?
Mom: Four Bobby...my mom, Jenny, your mom and Pat.
Dad: What about all the people we call mother?
Mom: How many people do you go around calling mother?
Dad: Depends on how close I am to them when they pull out in front of me.
I died laughing...My Dad is a witty man!
