Like a pizza!

Craig: grandpa we'll be there in half a minute!
Me: how long is that Craig?
Craig: well let's see... (Becomes deep in thought.)
Me: think about it how many seconds is a minute? Let's work it out.
Craig: Wait! 30!
Me: 30 what? (surprised).
Craig: Seconds! 30 seconds because, see I knew that 3+3 = 6. So if a minute is 60 seconds Then I just take one of the 3's away and I'm left with 30 seconds. I just chopped it right in half, just like a pizza! (then he emphasized his his point by slashing his arm through the air.)

Me: (after recovering from the pizza comment) um wow! Totally wasn't expecting that. But, that's my boy! Such a little smarty!
