The March 27 Saturday Night Live episode had a music video (see below) where Chris Redd raps playing one such cocky vaccinated senior.

In the New York Vulture, Rebecca Alter writes the pre-taped “Boomers Got the Vax” music-video “that may be the single most joke-dense sketch of the year so far. It’s a true ensemble piece, with everyone playing a different type of obnoxious old person with their own flow, all bragging about how they’ve been vaccinated”.
