A band/orchestra riddle is:
 
Q: What do you do when you don’t have any rubber bands?
A: See if you can find a plastic orchestra.
 
The joke was posted on a Laffy Taffy wrapper by at least 2005.
   
         
Wikipedia: Laffy Taffy
Laffy Taffy is a brand of taffy manufactured by Nestlé and sold under their Willy Wonka Candy Company brand. Laffy Taffy is a brand of candy first produced in the 1970s as “Beich’s (Name of Flavor) Caramels”, though in fact they were fruit-flavored taffy squares. The original company later changed the name of the product to “Beich’s Laffy Taffy”, which occurred some years prior to the acquisition of distribution rights and later purchase of the product line by Nestlé. The candies are small (about 1.5 oz or 45 g) individually wrapped taffy available in a variety of artificial fruit flavors, as well as a chocolate mousse flavor. The candy was advertised as having a “long-lasting” flavor. In 2003, Wonka introduced a variety called “Flavor Flippers”, a piece of taffy that had a soft center with a different flavor.
 
The name refers to both the texture of the taffy as well as its embodiment of silliness; jokes are written on the inside of each wrapper.

Dear Greta, DMV Employee at Window 8
Why must you be so insensitive to me? When I approached you, I was smiling. Do you remember this? Well, it was genuine. Unaffected by the stagnant air, uninfluenced by the loud wailing and lamentation of the gathered souls, I greeted you with a glee matched only by vivacious children on Christmas morning. I was overjoyed to be meeting you, a ray of sunshine in your eternal storm, a delicious candy cane for your stocking. Yet you couldn’t even take a moments break to share in my refreshing delight. Which is a shame, because I had been eating Laffy Taffy all day and my pockets were stuffed full of jokes.
