LAUGH, DIRTY, JOKES is good -- but no C/P/M/N which are all much more frequent than G/J/K/Y.

In my experience, Y is rarely difficult to place; it's almost always obvious when you're going to need it.

And you rarely need to think about J at all -- like with Q and Z, it's usually obvious when you need it. (Not many five letter english words have J anywhere apart from the first letter, and the few that do mostly have it in the second, like EJECT, or uncommonly the third, like MAJOR, though it might be more common in loanwords like BIJOU I guess).

Yep, I sometimes follow up with MANIC or PANIC if I've got too few letters, to test for C/P/M/N
