who fell down an out house and died
His unfortunate brother
fell down another
Now they're interred side by side

Lots of limericks in The Lure of the Limerick, by William Stuart Baring-Gould. It goes in and out of print, but it might be in your local library. Yes, even in this day of the Internet, there are still gems to be found at the library.
