Here's a more practical puzzle
-
You pull into Sonic, punch the little red button on the menu box and order a Route 44 unsweet tea, a small order of tater tots, and a corn dog. You ask for one packet of mustard.
They bring your order, just as requested. You put your drink in the cup holder, the tater tots on the dash, and you take the corn dog out of its paper bag, and place it on your leg. You then take the mustard packet, look for the "tear here" label, and try to tear the corner off. It won't tear. You try every corner, and it just will not tear.
How do you get it open....
