A much meaner trick is to reassemble the cube with only one piece flipped
or only one corner twisted.
There is no way to flip or twist only one piece - all the
methods affect two pieces. For greater effect, after you reassemble it so its
impossible to solve, scramble the cube so it won't be so obvious. When they
first came out, I knew someone who was quite obnoxious about bragging about how
quickly he could solve the cube - his best time was somewhere in the three
minute range. This trick sure shut him up.
