One funny forfeit could be having to eat a really spicy food that they don't like. For example, if someone hates super hot peppers, they have to eat a whole plate of them. Another could be having to do a silly dance in the middle of a busy street. It's hilarious to watch and very embarrassing for the person who lost the bet. Also, they could be made to wear a fake mustache for an entire day and talk in a funny accent.
Well, they could be forced to write a love letter to their least favorite co - worker. It would be both awkward and funny. Another idea is to have to go through a day speaking only in rhymes. It's not easy but it can create some really entertaining moments. Also, they could be made to take a self - portrait with a really goofy face every hour and post it on their social media. It would be a very public and funny forfeit.
A great forfeit is to have to tell a really cheesy joke every time someone asks you a question for a whole day. It can be really funny for those around you but quite challenging for the person who lost. Or, they might have to carry around a stuffed animal and talk to it as if it was a real person in public places. This would surely draw some strange looks. Another option is to have to do a handstand for one minute in a public park.
