Was reminded earlier that Johnny Carson's run on the Tonight Show ended on May 22, 1992 - 25 years ago - so I looked up what other shows ended that month (https://en.wikipedia.org/wiki/Category:1992_American_television_series_endings), and sure enough...
Night Court
MacGuyver
Hee Haw (was in syndication)
Superboy
Jake & the Fatman
The Golden Girls

And a mention of 3 notable shows that ended in late April:

Who's The Boss?
Growing Pains
The Cosby Show

GOMER PYLE: U.S.M.C. also ended in May-I read it on Facebook

GOMER PYLE: U.S.M.C. also ended in May-I read it on FacebookTMC was referring to shows that ended in 1992, the year Johnny Carson retired from the Tonight Show. Gomer Pyle was several decades earlier in the 60s.
