A colleague's eyes are always fresher than your own.
Too many times has a colleague been able to immediately pin down a problem I'd been pouring HOURS into.
(More junior) teammates often wonder why I'm so verbose with my status-reporting. I can't count the number of times where I've sent out a "I've been banging my head on , here's everything I've done - did I miss something trivial" only to have a reply, a few minutes/hours later, saying something as simple as "line 24 of your problem-description".
