Do you fly much?
You really don't see that many fat fucks on flights. It's too embarrassing for them. They can't fit through the doors, the aisles, the seats, or the bathrooms. They can't run for stand by down the terminals.
If they do fit their fat asses in a seat, they spill over into the passengers next to them. Nobody can move. If they fart, they are dead. Well... at least they should be.
