Thorne Smith 
Turnabout [EPUB ebook] 

The premise of 
Turnabout involves a husband and wife body switch, executed by means so trivial that even the author barely spends any time justifying it. The comic results, however, are snicker-out-loud funny, as the pair stretch and snap their gender roles to lengths greater than Silly Putty itself could bear. Sure, the effort is lightweight, but who really cares when Smith’s effortless style elicits so many belly laughs?
