Funny Naija Joke: The toothbrush between daddy's legs

A four year old girl walks in while her father is
dressing in the bedroom. She looks at his privates
and points at his ??? and ask, "Dad! What's that
thing between your legs?"
The dad replies, "I don't know."
She goes to the kitchen and finds her mom, "Mom.
What's that long thing between dad's legs?"
Her mom instead of explaining things to her,
replies, "I don't know."
A week later, when her mom was coming home
from work, the little girl ran to her and says, "Mom!
You refuse to tell me the name of that thing
between dad's legs. I have finally figured it out
myself. It's a toothbrush!"
The mom laughs, then ask, "How do you know
that?"
The little girl explains, "When I came back from
school this morning, I saw aunty Nana (the Maid)
kneeling in front of dad, brushing her teeth with
dad's toothbrush and sure enough, there was
toothpaste all over her mouth."
The mum fainted!
