When Master Julius wants an ashtray, a slave's mouth will suffice. When Master Julius gets bored with that, he will ash onto a plate, spit in it, and wipe his bare soles until the ashes are all on the bottom of his feet. Now the slave gets to be an entertaining ashtray as he licks his master's feet spotless! What a loser, enslaved by master's feet he'll lick them clean no matter what.
