A knighter can be converted into a math formula, so you too can execute this swindle!
x = Amount of money given to you
y = Amount of marijuana you confer to the buyer
--- = y
(For an added bonus, if the buyer is already under the influence of marijuana, it is acceptable to replace 2 with 3 or even 4)
Scott: no, this is 0.5, stop givin me nighters man
