It was to my hall room and went like this:

Me: 'Hello?'
Caller: 'Hi, im sorry if this sounds a little forward, but ive just been dumped by my girlfriend, and i thought- Hey! 'take a walk on the wild side'- you know how it goes- anyway, ive decided to phone someone at random and ask them out tonight, cause i dont want to be alone on valentines day'
Me: 'I'm sorry, I'm not gay'
Caller: 'You sure? We could still meet?'
Me: 'Bye!'

---end of call----

I'm not sure if it was serious or a prank, but boy, it was hilarious.
