We don’t like least common multiples

H.o.p. was relating to me one of his stories today (as he does everyday) and my ears lit up as he started talking about his cartoon characters undergoing a “dimension paradox” but I’m not supposed to post the details because he wants to keep it a surprise. I think I can relate it involves a black hole. (And a couple hours earlier he had been melting down at the prospect of trying to comprehend least common multiples, which also used to blow out my brain as a kid, and I have to say that never as an adult have I had to face lemon pies cut into 16, 12 and 31 pieces and deal with LCM thereof.)
