Here is a simple yet popular one.
Need: 5 Scouts (1 to be a table).
1st Scout comes out: Gets down on all fours, pretending to be a table.
2nd Scout comes out, looks at the table and declares;
2nd SCOUT: "Ahh, a fly, I think I'll pull it's wings off"
Proceeds to pick it up, pluck the wings, put it back on the table, and walks
3nd Scout comes out, looks at the fly on the table and says;
3rd SCOUT: "Oh, a fly with no wings, I think I'll pull it's legs
off", With great precision and animation, picks up the fly, removes
it's legs, and puts it back and walks off.
4rd Scout comes out, looks at the fly and announces;
4th SCOUT: "Say, a fly with no wings and no legs, I think I'll
pull it's head off." Then proceeds as the other Scout before him.
Last Scout comes out looks at the table, then carefully inspects the object
with out picking it up and says very quickly
LAST SCOUT: "A raisin !" and quickly picks it up and puts it
in his mouth
