N's unforgettable conversations

Trying to have a  conversation on  professions:
Me: I can sing. Who am I?
N:Singer
Me: I  can dance. Who am I?
N: Dancer
Me: I can teach. Who am I?
N: Teacher
Me: I can drive a car. Who am I?
N: Driver

This went on for a while. Then, running out of options & reminded of my adventure  sports days,  i started: I can climb walls. Who am I?
Pat came the reply: Lizard!
