Bob Uecker in case you didn't know, had (https://www.upi.com/Archives/1989/02/18/Bob-Uecker-who-broadcasts-Milwaukee-Brewers-games-and-stars/2171603781200/) what was described (https://www.nytimes.com/1989/02/17/sports/sports-people-baseball-uecker-recovering.html) as a "very mild heart attack" (https://www.latimes.com/archives/la-xpm-1989-02-16-sp-3750-story.html) on February 14, 1989 (https://www.chicagotribune.com/1989/03/03/ueckers-sense-of-humor-survives-heart-attack-intact/). So, that would've been in the middle of Mr. Belvedere's fifth season (1988-89 (https://en.wikipedia.org/wiki/List_of_Mr._Belvedere_episodes#Season_5_(1988%E2%80%9389))). Have you noticed (https://www.youtube.com/watch?v=7TtoeIiCVFU&lc=UgxCdmUrttCs5cFBv1t4AaABAg) that in the first several episodes of the show that were shot after he came back (beginning with the episode, "The Ghostwriter" (https://www.imdb.com/title/tt0651903/)), he's filmed with a ton of backlighting and is wearing pancake makeup?
