The Munsters1964

Herman Munster:
Alright, explain it to me, Grandpa, Lily's not here, but she circled Clyde's adress in the phonebook.

Grandpa:
Now why would she do that?

Herman Munster:
Don't you get it? Clyde told me he met a girl on a bus. Right?

Grandpa:
Right.

Herman Munster:
Clyde never told me the name of the girl he met on the bus. Right?

Grandpa:
Right.

Herman Munster:
Every day, Lily takes the bus to go shopping. Right?

Grandpa:
Right.

Herman Munster:
And Lily acts very funny every time I mention the name of Clyde!

Grandpa:
Hmmm.

Herman Munster:
So, fears to witt and ergo, the girl on the bus is Lily, and I have been helping sly old Clyde romance her with my letters!
