OK here's a topical one ....
Go to hardware store and get a cheap white painters coverall, one with head bonnet and booties. Get a basket, a towel, a bottle of Dawn and a stuffed animal ... perhaps a Pelican or Duck or Sea Turtle. Also see if you can still get that gooey plastic stuff, Slime or Gak, in brown or black (or make your own, Google it). Dress the kid up in overall, dirty his/her face with brown/black makeup. Slap some Slime all over his coveralls and the stuffed animal. Put the animal, towel and Dawn in the basket. Voila your a Gulf Coast shrimper ... errrr ... cleanup worker.
