Hi Joe, Whew! Took me a bit to find it! While both Sophocles and Plato has some work espousing immoveable objects, I'm pretty sure ZENO was the trouble maker who initially proposed the issue by asking what happens when the irresistable force meets an immovable object. He was like that. <shrug /> Some say it was Frank Sinatra who answered the question when singing Johnny Mercer's 1955 song - Something's Gotta Give ... "When an irresistible force such as you meets an old immovable object like me." Then there's always H.L. Mencken's quip: Temptation is an irresistible force at work on a movable body.
