I lost my ball...

Evan was worried that he lost a ball tonight. Here's how the conversation went:

Evan: I need to talk to Daddy (who was in the bathroom)
Me: Why?
Evan: I think I lost my ball(Daddy flushes toilet, then...)
Evan: Nevermind
Me: Did you think it was in the toilet?
Evan: No it's in my pants
Me: It fell in your pants?
Evan: No, it's my privates
(silence)
Evan: You know...., my balls?
Me: Talk to your father!
