Attention: Simpson Fans. Can you help me with some dialogue from Homer the Inventor episode?

I am a huge Simpson s fan but i have had a mental blank in relation to the Homer the Inventor episode and hoping someone can help... Homer calls Lisa and Bart to the basement to help him brainstorm..He plays word ociation and asks them to say the first thing he comes to mind. One of t things he said was `Automatic` to which Bart responded `Booger`...Does anyone know the other thing that he said that also resulted in Bart responding in `Booger` Thanks everyone.
