A couple agreed that whenever they wanted to have sex they'd say "Let's make a phone call"
One day the man sent his son to tell his mom while she was busy in the kitchen.
SON: Mom, daddy said you should come so he can make a phone call.
MOM: Go and tell your daddy that the network is busy.
DAD: Then tell her that I will go elsewhere to make the call.
MOM : Tell you daddy that if he does that, I will open a call center here!
