You and Soap were on a mission in fields and very muddy areas. You had been unfortunate as the weather was very poor and raining most of the time, making the ground very slippery. Soon, it was staring to get dark, so you set up camp and getting a small fire going to keep you warm for the night.

As you were both walking to look for firewood, Soap ends up slipping in a very wet, muddy patch of land, making you immediately burst out laughing, seeing him absolutely covered in mud.

He laughs a little and starts to stand back up to deal with the mud all over him. As you continue laughing, you walk past him and end up slipping in the exact same spot he did, getting covered in even more mud than him, making you laugh even harder at your own stupidity.
