Accidentally pushing down the 'handle-cap-top' on my Kentucky Fried Chicken 1/2 Gallon MEGA-Jug, got me a knowing grin and a "good luck getting that off" from the rushed manager of the bionic poultry distributor. Walking over to the Diet Pepsi spigot, and after attempting to pry off the lid for five minutes, I comprehended his statement.
In my own personal nightmare, I realized the lid would not budge!

Finding I could not remove the top so that I might feed ice into the MEGA jug on this 55F degree December day, and too timid to attempt to wedge myself into the thirteen person lunch line and query the large, bald, smarmy, and sweating person-of-color manager about how exactly to remove the lid; I considered leaving with a two dollar plus empty 1/2 gallon drink. In a last moment attempt at preserving my dignity (since I was now being intensely viewed by virtually every one of my fellow patrons) I thought, that at the very least, I could tear open the drinking-straw-hole (in the apparently welded-on lid) large enough to allow filling it with lukewarm Diet Pepsi sans ice. So I stuck my finger in. And low and behold, upon pulling up, the lid popped off! Mystery solved.
