I always laugh a little when I found a comment like:
//TODO move this somewhere else
And it literally says "somewhere else", the original developer knew it was a bad place but didn't know where was a good place, so with that comment it's automatically fixed and pasted there forever. It's more funny when you find it in a codebase that's grown a lot over a few years and you think about how many people saw it and didn't want to take the risk of changing it, possibly introducing bugs. Also, it's even more funny when you realize you're one of them... it works there, there are bigger problems in the code, so it's not that bad. Anyway, it has a TODO comment, it will be done some time in the future... right?
