I still laugh out loud when I recall the tale of Mortimer’s maiden aunts and their well-intended plot to send nice old gentlemen to meet their maker via a glass of “laced” elderberry wine (and then have their addled brother Teddy, who imagined himself to be Teddy Roosevelt, bury them as yellow fever victims in the Panama Canal, aka the basement of their oh-so-proper Boston home). Whether you’ve ever seen the film or not, you can enjoy Joe Kesselring’s original play onstage currently at the Showboat Majestic on the Public Landing. Wednesday-Sunday. Through July 1. $17-$18. 513-241-6550, showboatmajestic.com.
