Are those your favorite words?

Aiden's expansive vocabulary seems to have hit a developmental hitch. The end of our conversation this morning went like this. 

Me: Are those your favorite words?

Aiden: Yeah.  And spit. Poopy, pee pee and spit. 

And so the potty "humor" is in full effective at our house....with no end in sight, ever, based on gauging what all adult males in my life find to be comical.
