in thread What this pattern matches

First, let me say that this is one of the best explanations of a regex that I have seen.

Now, can anyone give a good example of 1 or 2 lines that would match and 1 or 2 that would NOT match?

Allow me to reword and provide a possible match example:
Match a line with at least one underscore (if more than one, the following applies ONLY to the LAST underscore) that is both preceeded AND followed by at least one character.

Match: I_love
Match: I_love_perl
Match: I_love_perl_!
No Match: I_love_perl!_

Am I right?
