Probably the most telling thing about RiceGum out of those clips in idubbbz's video is how he says his whole channel is just satire. It's like he knows everything he does is absolute stuff, but isn't willing to admit it to himself or anybody else.
Also his idea of how normal people live is just him walking around his mansion but without his sweater on is probably a good approximation of how rich people see the rest of the world, but t h a t ' s a w h o l e o t h e r d i s c u s s i o n.
