You simply put your arms on the floor, because you don't have an inventory system in which to store them, and frankly, you're too cooked to come up with a new one. You wait for your always reliable, if chronically stupid PEANUT GALLERY to tell you what your inventory system is, because you're going to be brutally honest.
20 years of clownery has left your imagination a little crispy. Sure, you COULD come up with one, but what's the point? "Heheh..heh.he... you park the arms in the VIP PARKING SPACE in your vaunted HAVENUE! Heheh... because now you HAVE them. Hahehh.. hueh." Fuck off. Literally actually fuck off and grow up.
Oops, your shitty morale is showing again. LOL! Forget that weird shit just happened. The point is, within seconds of putting your stupid arms on the floor, there will be literally hundreds of brain suggestions for where to put your arms from your loyal gallery.
