A joint that seems to last forever, the joker is an extra large cone guaranteed to spread a grin from ear-to-ear without straining the finger muscles.

 

Stick two papers together with the gummed strips forming a straight line.
Take a third paper and fold it in two, leaving the gummed strip on the outside.
Wet the glue and and sandwich the folded paper firmly between the other two as shown.
Before the glue dries pull the paper out. It should have left enough glue to stick the others together.
Stick a fourth paper to the lower, righthand edge of the joint as shown.
Add a fifth paper to the end of the joint as shown.
Create a more triangular shape by tearing the fourth paper diagonally in half. Refolding the papers along the centre of this triangle will also ease rolling.
To support the extra length use the whole of the forefingers when rolling. Prepear for top-notch enterainment!
