This is hilarious.
How to catch a goodie two shoes boy: pretend to do tax evasion.
I can't stop laughing. This is too good.
Also the bills and sentences for tax evasion are ridiculous, don't do tax evasion. You can get in bigger trouble than for murder.
i heard that japanese tax agency are cut throat too, i also heard that jp people have a habbit of collecting payment receipt so that they can calculate their tax
