Instagram for fun!
If you are interested in getting a smile or a good laugh get onto some Instagram tags. Try typing in #funny, #humor, #funnypic. Then try to see if there are more then one from a person. Then if you like them follow them. There will be other tags from there that will get you closer to the type of pictures and short vids that are for your humor.
There are always pictures of cats and dogs. But there are some of very funny ones of cats being scared or a dog and a vacuum cleaner. There are some really funny and warm ones of panda bears or baby tigers that are fun.
