I'll pay you back next week.
If I lose, I'll inhale enuff oxygen and then just blow into some empty gas cans I have in the basement. So if I don't win, I'll get you back 5 oxygen tanks worth of hot air by the end of the week.
I see a huge air bet coming up. 50k air units. Please lend me the oxygen tanks.
Yours truly,
Sir Air A Lot
