The phrase "Tom, D and Harry" is a placeholder for multiple unspecified people; "Tom, D or Harry" plays the same role for one unspecified person. The phrase most commonly occurs as "every Tom, D and Harry", meaning everyone, and "any Tom, D or Harry", meaning anyone. The masculine names in these phrase do not in themselves imply exclusion of females, but use of either version when the context implies necessarily being female − for example, "Your mother could be any Tom D or Harry" − would normally be seen as careless or ironic.
Tom, D and Harry (1941 film)
Tom, D, and Harry are the names of three mountain peaks in the Cascade Range in Oregon, U.S.A.
The phrase is also used by english speaking medical students in memorizing the order of an artery, and a nerve, and the three tendons of the flexor retinaculum in the lower leg.
I could go on and on, but won't ;)
