What's my name again?

My kids knew my name was Michael since day one; but for a while now they have called me Michael Jackson every time I walk into the classroom. It was cute and all but now one student started calling me the "The King of Pop" because that's what his mom said about Michael Jackson. Pronunciation is still a struggle of theirs. But now "The King of Pop" has gone to "King of Poop," which has then to turned to "King of Caca." Ugh...I knew that one time in preschool, when I had an accident that it would haunt me for the rest of my life...
