Professor Cheers Comedy Rope Trick

Prof. Cheers Comedy Rope Trick
 
A small piece of rope is seen in your left sleeve.  You pull and
continue until about 20 or so feed of rope comes from your sleeve. 
Wait a minute, it's stuck.  The rope is then pulled up your trouser
leg through your original sleeve.  Wait a minute, it's stuck again.
The rope is pulled from your other trouser leg.  Wait a second,
that is impossible.  Wait a minute again, stuck again.  You pull
and at the end of the rope appears a pair of men's (or ladies) shorts.

 Great Trick
