What word do u think is funny?

I am only 40 y o , but my dad would watch Gomer Pyle and he always said "SHAZAM!" I always like the word "thingamajig"! That word makes my husband go nuts because when I want him to get me something that I cannot think of, I use that word. My son tells me that he cannot get it (whatever I am asking for) because he says everything is a " thingamajig"! He is 20 y o, and definitely has his own opion.
