I used to work with a guy that would put the verb at the END of a function name, rather than the beginning.  For example, rather then "GetSupportedVersion", he'd use "SupportedVersionGet".  Of course, I know plenty of people here will say it should be "get_supported_version", but that's another discussion entirely.

Another guy would frequently use "Grab" instead of "Get".  The fact that he used a different verb than the common convention though wasn't NEARLY as infuriating as the fact that he was inconsistent about it.

My favourite was from a guy I worked with years ago.  In C but I'm sure 
you'll enjoy it.  In all functions, something like:-

int flag = 0;
if flag {
     printf("\nthe string");
}
else{
     printf("the string");
     flag = 1;
}

At least I think I've got it correct, too lazy to check, sorry :)

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.

It looks like a sys.stdout.softspace hack in Python 2:

  print line, # comma!

Ah, you youngsters...  :-)

Using a bool to index into a list used to be the standard idiom, before the
ternary if was added to the language. So I don't consider it "weird",
especially as a lot of my code still supports Python 2.4 which doesn't
include the ternary if.

Sometimes, instead of a list, I'll use a dict:

    {True: value1, False: value2}[flag]

to emulate ternary if.
