Why do Susan and Mike call they son MJ? As आप remember they were going to name his Mainord...

His full name is Maynard James Defino and he was named after Mike's grandfather who had died and Susan didn't like Maynard but she decided to stick too it because Mike wanted it.
So they call him MJ for short I think because Susan doesn't like the name Maynard.

i think it is mainord junior या sometjing like that;D

His suns original name is Maynerd in honor of Mike's dead grandfather. They call him MJ of course. It would be embarysing for him to be called May या Nerd!
