@Moodyz - well, he massacred an army of goblins just yesterday. I don't know why he keeps looting their underwear (probably as a a stock of food for cleaner slimes), but that should be enough for a whole advertisement campaign.

It's free real estates japtems. Even the poorest cloths can make a decent cleaning rags, and in the adventurer job, you never have too many of them.
@lyndine2009 I imagine if you had a magic storage box and lived alone in the woods with no means to buy or barter you would hoard all the materials you found, no matter how gross. Also, if he has had cleaner smiles for a while, he could always clean the cloth and then repurposed it.
I know there is also the japtem inventory thing in games, where you collect drops mindlessly irregardless of whether they are useless or not.
