Bennett begins to develop a sense of humour

Bennett: Dad, what does repeating mean?  
Me: It means saying the same thing over again.
Bennett: Dad, what does repeating mean?  
Me: It means saying the same thing over again, Ben.  
Bennett: Dad, what does repeating mean?
Me: Ben! It means – okay I get it. Hey, go do that one on your mom?  
Bennett: Hey mom! What does repeating mean?
Mom: Ask your dad!  
Bennett: Hey dad -  
Me: No. Just, no.s
