Recently, I was trying to think of all the times that Homer adds an extra syllable to words. Here's what I have:
saxamaphone (Lisa, stop playing that stupid...) obamabo (trying to figure out what instrument lisa plays) tubamaba (trying to figure out what instrument lisa plays) tramapoline, trampopoline (excited about free trampoline ad in paper) metababolism (younger Homer can eat whatever he wants because of it) sophistimicated (THOH - the matter transporter) macamadamia nuts (free cookies at the mall - he also wrote a note with that spelling)
Did I miss any?
