Well of course you should! And struggle with getting back up so that you can fall back in the mud with your butt - in whatever you're wearing right now.
Never, ever, fall face first into anything until you're sure where the is and what's on the bottom. For example, it there's a rock just below the surface, you could open up a nasty gash in your forehead. And if it's mostly water and the rock is a few feet down, you could break a vertebra in your neck and end up a quadriplegic.
In my former life, I had to visit young men in the spinal cord injury ward. Not a happy experience.
Are you going to start doing muddy videos? I like your pie stuff.... but I would LOOOOVVVEE to see you fully naked just rolling around in the mud. You have a rockn' body.
