The Taco Bell mention was sardonic, or in today's lexicon, ironic humor.
The reason this is actually funny, is because of the juxtaposition between my unique insight into what may be driving the recent price surge (vomitoxin diagnostic testing) and the specific mention of a widely-know eatery which no one would ever admit eating at. McDonalds not funny, Taco Bell funny.
You must be a blast at cocktail parties. Do you have Aspergers?
