Ear plugs please

Ugh, someone get me some earplugs! I am sooooo tired of hearing morty pretending to be a fire truck I can hardly stand it!

Does he do this JUST to make me feel crazy or am I just imagining it?
The strangest part about this annoying phase of his life is that he thinks he is a British fire truck none the less?!!
He has never even been to the UK!

All i hear morning, noon and night is.. Naw Nee, Nee Naw, Nee NAW!!!!!!!

Can't we move on to motorcycles or something?!
