I'm actually in the guinesses book of world records, although not for a record I broke all by myself, and my name isn't printed in any of the books.
A few people in my town got lots of members of the community to help break the record for largest foot painting a few years ago (basically finger painting but with your feet). I was out of town the day the final painting was shown to the public in a large field at a local park (its so big they couldn't permanently display it anywhere) but a drone caught a picture of the whole thing. That record was broken in 2015, but after doing a search on the Guiness World Records website it was beaten about a year later by DBS Bank Hong Kong Limited. :/
I've also submitted animal/pet photos to two seperate National Geographic Kids magazine world record attempts (both of which they succesfully got the world record for) a number of years ago when I used to read that magazine as a kid.
