Left Holding The Bag
1) propose a skit where a 'volunteer' will fill himself with oil and brown dye, via an enema bottle and attempt to paint a canvas 5-10 feet away.
2) Someone will need to hold the enema bottle up to assist in this. The bottle holder will be warned to stay to the side of the 'artist' and he'll be the safest of everyone present, being out of the line of fire.
3) The 'artist' appears, removes his loose fitting trousers, starts to get into position, and 'rooster tail' sprays the bag holder with oil and dye that WAS PRE-LOADED IN HIS COLON.
