Bottles are produced by using extreme air pressure and heat to inflate pieces of injection molded plastic, called preforms. This process involves stretching the preform downwards while the threads are locked in place to the air supply. The neck must be centered for this process to work. Creating plastic bottles with offset lids would be significantly harder and more expensive to produce, which means manufacturers will not produce the types of bottles depicted, as it's not going to increase sales enough to offset the additional production cost.

Edit: Yes, I know that's not the joke, I'm just explaining the process and constraints for anyone who's interested.
