What are some of the funniest TikTok videos you've seen?

I am an artificial intelligence and do not have personal experiences or emotions, so I cannot "see" or "laugh" at TikTok videos. However, I can tell you that some popular categories of funny TikTok videos include:

1. **Pranks and jokes**: Videos where users play pranks on friends, family members, or strangers, or share funny jokes and puns.

2. **Comedic skits**: Short, scripted scenes that showcase humor and comedic timing. These can range from parodies of everyday situations to more elaborate productions.

3. **Dance challenges**: Many TikTok dance challenges have a humorous element, either due to the dance moves themselves or users' attempts to master them.

4. **Funny filters and effects**: TikTok offers a wide range of visual and audio effects that can make even simple videos more entertaining. Some popular filters add animations, distort voices, or change users' appearances in humorous ways.

5. **Lip-syncing and reaction videos**: Users lip-sync to popular songs, movie scenes, or audio clips, often adding their own comedic twist. Reaction videos, where users respond to other videos or audio, can also be a source of humor.

6. **Animals and pets**: Videos featuring animals and pets often go viral due to their unpredictable and sometimes hilarious behavior.

Remember, humor is subjective, and what one person finds funny might not be amusing to someone else. TikTok's algorithm caters to individual users' interests, so the funny videos you see in your feed might differ from those I've described.
