Trap and rescue (me)

I came in for my evening shift the other night, and overheard the end of a conversation with one of the desk staff.  A little boy, maybe 4 years old, was looking for a "trap and rescue" book. Hmm, trap and rescue?  I wasn't sure about that (maybe everyone knows about trap and rescue but me) but he seemed satisfied with a couple of emergency rescue books. 

Then he came up to me and wanted the "trap and rescue everything" video. Yes, he was very sure that this video existed and, no surprise, this title doesn't actually exist in our catalog and there wasn't going to be a very informative reference interview. So I took him over to the videos and dvds and we looked...for a longggg time. We couldn't find the "trap and rescue everything" video, but I found him other rescue av material and we had the following conversation:

Me:  "Here's water rescue."
Kid: "I think I've had this one but I still need the other one." (he held up 2 fingers)
Me:  "Okay, but we don't have a trap and rescue everything video. How about air rescue?"
Kid:  "That's good. But I need trap and rescue everything."
Me: "How about emergency rescue? That's got a lot of different rescues."
Kid: "Yeah, that's good, too, but I need trap and rescue everything."

We were stuck in a friendly though endless loop.  After lots of conversation, he did take 1 video and 2 dvds that we had found (yay!) and finally his mother appeared and said, "Great! You're so lucky because you can take out 3 movies!" To which he replied, "No, I only want to take one. And I want the other ones to wait for me here with my name on it until next time."
