I've always had a fascination with robots. I wanted to build one as a child. The closest I got was realizing that microchips are made from silicon which is made from sand. Turning the sand into silicon and then microchips was a bit beyond my capabilities. I did take apart a Speak 'n Spell, thinking I could use it as the heart and voice of my robot. I instead ended up with a broken Speak 'n Spell.
It took me this long to realize how easy it was to create a robot with an overpriced pen.
