<human>: Can you summarize the given text in a few sentences?

So this happend about 5hrs ago! I'm a student and take art, it's One of my favorite subjects and the class is full of pretty good... People, I don't know them well enough to be friends but one of them is my best friend and the other is a girl I had a crush on for about 3 years, anyways, I was painting a small dot of blue on a scrap piece of paper to make sure the blue I was using was similar to the blue on the photo.

Here's where IFU: I forgot I had made this small dot of blue on the paper and proceeded to lean my elbow on it, I didn't realize this at the time so I continued painting when I noticed a blue, elbow-shaped paint mark on my painting in the bottom Right, where id been resting my elbow, I look down and see somehow the small dot of paint I had made had covered my elbow, so I do the 1st thing I think of and wipe it off with my left hand, my friend is now laughing as he sees my painting, my elbow and my hand covered in a smurf-like blue, I am laughing at myself but am annoyed at my stupidity. It being a very quiet class, everyone now turned to me and my friend laughing like mad people and me describing how it looks like ive squashed a smurf. Others start laughing so I explain myself to the class... Here's where IFU again, I facepalm during explaining myself... I now have paint on my forehead, cheek, in my eye, left hand, Right elbow and on my painting... I get embarrassed (still laughing at myself though, it's always Good to be able to laugh at yourself) and I then walk over to the taps at the side of the room to clean myself up.
<bot>: painted myself blue by accident, cocked up and laughed at by a class of 21 people including my close friend, an old crush, and a teacher! Don't paint, kids!
