I called my dad to tell him to be on the lookout for a package from me, but that he can't open it until father's day. He called me on Saturday:

Dad: I got a package from you. It's from a chocolate place. Can I open it.
Me: No Dad! That's you're Father's Day present.
Dad: What am I supposed to do with it?
Me: Put it in the refrigerator until Father's Day!
Dad: When's Father's Day?
Me: It's on June 20th.
Dad: Well that's not fair! What if I get hungry before then!
