On their way back to the office from their offshore trip, Bongo and Mr. Jim stopped by the "Billion Barrel Monument".  Mr. Jim said it was to commemorate the production of over a billion barrels of oil from the field.

Bongo wanted to know if a "billion" was more than 5.

Bongo can only count to 5...then he gets confused.

Mr. Jim assured Bongo that a billion was more than 5.

Bongo was impressed.
