Does holding a glass to a wall work?

Why does holding a glass to a wall work?

The reason this works is that you create an "acoustic coupling" between the wall and the glass, allowing sound waves to travel from one side to the other. A soda or beer glass works best. Some eavesdroppers also swear by Dixie cups, but glass seems to conduct sounds better than other kinds.
