The funnies thing that's happened to me this year was on New Years Day...
Given the drunken nature of our night, one of my mates dropped his phone into his grog. Thinking it best to try and clean it before letting it dry, he ran it under the tap for 5 minutes.
Next morning, sitting around the table, he pops the battery in, and low-and-behold, it works (albeit with some keys not working properly, and the screen a bit funky).
Anyhoo, next thing we know is the phone has randomly (without any buttons being pressed) put itself into Photo mode, takes a (perfect) picture of me, then tries to send it to 'Mike Mobile' out of the Phone Book.
Between the hang-over and the laughter, I was in pain for quite a while after that one
He had to rip the battery out of the back because the Cancel button was one that didn't work properly
