This one comes straight from the recent Olympics, courtesy of CBS news.  After Usain Bolt won yet another gold medal, a spectator was interviewed and exclaimed “I’m on top of the moon.”  This is a congruent conflation of “on top of the world” and “over the moon”, both meaning to be extremely excited and happy.  All he needed to add was “Ma.”  My guess is that if Neil Armstrong knew about malaphors, he would have said this beauty instead of that “one small step” crap.  A big thanks to Sam Edelmann, whose keen hawk ears heard this one and passed it on.
