Nim: February 29 only happens every 4 years, so today is a gift from God.
Con: Every day is a gift from God.

Nim: Yeah, but this is like an infomercial.
(TV: You'll get God's gift of 365 days every year!!!)

Nim: Then the infomercial announcer guy says...
(TV: But that's not all!!! You'll also get one extra day...FREE!)
Nim: Yay!

Nim: What would the shipping charges be for a free day?
Con: That depends. Do you want it delivered overnight?
