This video uploaded to Youtube has more than 3 million views, and shows a man who really, really loves trains.
It was first uploaded two years ago, but it's going viral again.
First he's freaking out over the one train he's waited months to see.
Then suddenly he realises, another train is attached to the back of the first! He can hardly contain himself.
At one point, he talks about the chills he gets, but insists "that doesn't stop a foamer*" in almost orgasmic tones.
*A foamer is a railway enthusiast.
Watch the whole video here.
