It is not Kleenex, it is tissue paper; cotton swabs, not Q-Tips; acetaminophen, not Tylenol; ibuprofen, not Advil; ASA (acetylsalicylic acid), not Aspirin. Interesting side note: heroin was actually the brand name of diacetylmorphine, though in common vernacular the brand name replaced the medicinal one, like Tylenol, Advil and Aspirin.
EDIT: Oh and carbonated beverages? It's called
pop not
soda. Silly geese.
