On a flight to Manila, Juan sat beside a sexy lady who was reading a book on sexual statistics.
JUAN: That’s an interesting book.
LADY: Yes. I learned a lot from it. I learned that among the ethnic groups, the Muslim Maranaws have the biggest average in penis size, and the Batangueños have the longest average in penis length. They’re great lovers. By the way, my name is Grace. What’s yours?
JUAN: I’m Abdul Dimaculangan from Lanao and Lipa.
