Can I get hats in random drops?

I think I read somewhere that with a premium account you could get hats in drops as well as weapons.
I have now 50 hours of premium gameplay, and I never received one.

Was I mistaken? Or are the odds really low?

Free accounts can't get hat drops. As I recall, you upgraded to a Premium account (and gave @badp the Professor Speks... jealous), though.

There are 3 drop timers:

1. Items. Standard is 6-8 a week, assuming you play at least 6 hours a week. Note: To my knowledge, paints and tags are part of this timer, but they have a lower chance of dropping. Immediately following an update, Valve tends to raise the drop rate for those items. Right now, you're guaranteed to get 1 Uber-update weapon a week minimum.
2. Crates. Standard is around one a week (sometimes two), assuming you play at least 6 hours a week.
3. Hats/Misc. Standard is one every 1-6 months, assuming you play at least 6 hours a week.

The length of time that counts towards your next drop is limited to (iirc) 6 hours per week, but if you don't play for a week, the next week will be limited to 12 hours.

Hat drop rates vary wildly. I've had an 8 month stretch with no hat drops before, but more recently, I've been getting a hat every 1-2 months.

Side Note: The hat drop rate is bugged during the rare Double Drop rate week. While the first hat drops at the normal rate, the second uses a much, much shorter timer (the crate timer?). So, it's not unusual to get two hat drops during a double drop rate week.

It's totally random, but very, very rare (for many people). I get one hat in every couple of months.

(I did receive an Ol' Geezer the other day, but the last time I got a random hat drop was five months ago...)

Yes, hats are dropped similarly to weapons. However, little is known about the drop rate for hats.

For weapons, there is a rate of roughly 8-10 items per week, if you play an average amount of time.

However, hats (and paint, tags etc) are on a completely different kind of timer, where once you find one it can take months before you find a new one.

In my years of owning the game (so suffice since drops were implemented), I've only found two items on the hat-timer.

These posts seem out of date after a whole year, I have been playing TF2 for well over 600hrs and have had 1 hat drop for me, at least that's what I thought but it ended up being a achievement reward.

So, no, I haven't found anything in drops except weapons and crates, no hats nor any unusual items.

I've been premium for less than a week, and I've gotten 2 hat drops.
