Advanced grifting techniques

Texas Well Baby may be an attempt to gain charitable donations from a personal tragedy, much as Jessica McClure did after falling down a Texas well as a young child.

According to the Urban Dictionary, the Reverse Jim Gaffigan is the sale of individually wrapped Hot Pockets as a street vendor. Hot pockets are not normally packaged for individual sale.

Brown Betty is a type of cobbler dessert with fruit and sweetened crumbs. It also has a number of progressively more disgusting definitions in the Urban Dictionary. How any of these are connected to a grift or scam, I do not know, though mixing definitions could support User7812's theory that it is a food contamination hoax.

My instinct is that the "Brown Betty" is some kind of Food Contamination Hoax; where you place something unpalatable inside something you've bought in the hopes of getting compensation from the vendor. There have been some notable non-scam instances of this happening.

The "Texas Well Baby" would presumably be based on pretending someone is stuck down a well (the modern variation is that someone is stuck overseas) in order to solicit donations from concerned parties. There are, of course real instances of this occurring.
