The truth is, they are. (So says Wolfie)
I have to admit, I started this. But here is a list of jokes we made up, all riffing on the idea of a key:
What do you use to open a monastery?
A monkey (Monk-key. I told this one, but did not make it up.)
What do you use to open the door to a party?
A Funky. (This was Wolfie's.)
How do you open a glue factory?
With a sticky (Dad)
How do you open Klaus's room?
With a dorky (Wolfie)
How do you open Wolfie's room?
With a stinky (Klaus)
What do you use to open the Australia Zoo?
A crikey (Okay, I admit, that was mine. With apologies to Steve Irwin's family)
What would you use to open New Zealand?
A kiwi (Klaus)
What would you use to open Rivendell?
A Keebler (This was Dad's)
And after that, we just had to give up! LOL
