When using DBI, my database connection handle is always named $dbh. This might not seem too superstitious (after all, if my code looks like the example code it should be easier for others to follow), but I confess that I break into a cold sweat at the very thought of using any other variable name.

Then there's my SQL statement handle, $sth. What if I'm writing a program that uses multiple statement handles? I'm sweating already...
