Memes such as this one have become a new form of comedic entertainment, likely having the potential to revolutionize the marketing industry of the future. These funny and concise tidbits of humor serve to put a momentary smile on our face and chuckle to ourselves as we go about our lives.
Unfortunately, as outlined in the novel the Selfish Gene, memes are forms of cultural evolution that are much like an organism in that a meme's lifespan is inherently limited. Let's get this bread likely won't be around forever and the beauty of memetics is that another meme will come to take it's place.
