Ok, first off, make a list of five beloved things from your childhood. Leave room for a few entries below each thing you list. These could be toys, games, characters from a comic strip. Something iconically childhood related in your eyes. Examples: Any character from the Peanuts, Hula Hoops, A favorite park, Stretch Armstrong, Robotech, a character from My Lil' Pony.
Go through your list and make a list below each of these entries about three to four ways you can deal with each of these that feels like a subtle transgression against your childhood. Something that's just wrong enough to make you feel uncomfortable, but won't make the neighbors call the police. Examples: Charlie Brown in a strip club (I'm looking at you G. Murray Thomas), getting excited by the motion of a hula hoop, finding a dead body at Griffith Observatory, Tiny's Dream Date with Yellow Dancer.
Pick the one that makes you go "Oh, really?" and make that squishy face the most.
