The Best Burlesque Sketches: As Adapted for Sugar Babies and Other Entertainers by Ralph G Allen ISBN: 1557831890
Allen wrote the hit "Sugar Babies" from the more than 1800 burlesque sketches that he collected as an academic--basically, a theater folklorist--in fact, his credit on Sugar Babies is often given as "Adapted by Ralph G. Allen from traditional material"
This book is out of print, at least as far as I know, and hard to find, but is the only collection that I have heard of of this material, save the actual sketchbooks that the comics used to keep--
Oh, I almost forgot, you actually wanted some material!-Here are three gags you've heard before:
First Bit:
Injured Man crosses stage in assorted bandages and casts.)
Comic: What happened to you? Injured Man: I was living the life of Riley. Comic: And? Injured Man: Riley came home!
Second Bit:
(A Buxom Girl drops her purse, and a Comic tries to politely return it.)
Comic: I beg your pardon. Girl: What the hell are you begging for? You're old enough to ask for it.
Third Bit:
(Minister walks up to a beautiful young woman.)
Minister: Do you believe in the hereafter? Woman: Certainly, I do! Minister: (Leering) Then you know what I'm here after!
