Get a Wasteman mug for your fish Günter.
He’s the guy that expects the world but gives zero back.
He wants for nothing unless you’re paying.
He’s out for a deal wherever he can find one.

He’ll stay at with you and your gf but ignore your gf.
He’s tardy with time and expects you to drop plans with your gf to watch him try on suits.

He’ll speak to you once a year (when he wants you get get him something) and make you best man.
