Alka-Seltzer

Appeal: pathos- humor (lots of different stomachs in strange circumstances
(Associates laughing/smiling with alka-seltzer)
Fallacy: Argument from omniscience- says that it works on all stomachs, while it doesn't present any statistics supporting this (it's a generalization)

Country Corn Flakes

Appeal: pathos- the person about to kill the cow is unable to do it, so it makes the audience happy, and therefore associating happy endings with Country Corn Flakes
Fallacy: argumentum ad populum: the fact that they're called "country" corn flakes does not actually mean that people from the country would like them, or that country people are supposed to eat them

"Chain Gang" by Sam Cooke

The message of the song is that people of the time feel like they're having to work too hard at their jobs and they feel as if they're trapped, but that maybe it's really not that bad. The "chain gang" could be hyperbolic to create a satirical message. Sam Cooke is saying that life for the majority isn't so bad, and that at least when people are working at their jobs, they're not actually in chains, while the minorities are being actually suppressed. He says it needs to change, and the majority should realize the struggle of the minorities instead of complaining about their lives.
