Why did the Generalissimo…

…shoot the pigeon?

Because he was staging a coo.  

And why did the Generalissimo shoot the clock twice?
Because it was staging a cuckoo.

Why did he shoot his German wife, from whom he was separated?
Because she was estranging.  Ach, du.  

The barnyard realtor?
Because he was staging a coop.  

All well and good.  But why, then, did he shoot the warden who, in his spare time, dabbled in cooking?
Because he was caging a stew.
