I like the play on "high life" to "low life" with a bum character but "MULLER" is a term associated with milling grain. I wonder if the original intend was to be someone who mulls where mull is defined as: to make a mess or failure of. But, alas, there is no real word "muller" like that. I like the character and tag line reversal, but maybe only half a star for the product parody itself. This is one of those stretches.
I found reference to a Muller beer distributor in Philly, which makes me wonder if this one could just be an inside joke of some sort. Miller/Muller, Brewerytown/Bowery. Could help explain why it's not that great a wacky. who knows.
"The name of Muller has long been associated with beer in Philadelphia. Members of the Muller family grew up in the Brewerytown section of the city and, beginning in the 1800s, worked in breweries and delivered beer in horse-drawn wagons. Jack Muller, the founder of Muller, Inc., started in the beer business in 1938 with the formation in Philadelphia of Holmesburg Distributing. Located in Northeast Philadelphia, Muller, Inc. is a six-county Importing Beer Distributor and one of the nation's largest distributors of malt beverages."
