I used to clean out my car and find that the change in the cup holder was sticky from fast food cups that got left too long. I'd put the money in soapy water in a jar to soak and say that I was laundering money.
I just had an amazing insight: Atlus loves to reuse the demon models/animations in all of the Shin Megami Tensei games! You'd think they'd update them just a little, because some of them (Abaddon, Satan, Girimehkala, etc.) are ugly as sin.
