There's a full video of the event, there was also a dunk tank, no other mud (what a waste) and prior to this one of the audience girls says she'd do it IF she had a change of clothes.
Fun, thought a shame that someone from the audience blocks the view of the girl in the SWAT shortie catsuit getting sat in the mud for the first time. Great overall though!
Great find! Was that a mud dunk tank, or just a regular dunk tank that got dirty? I love a nice dirty or muddy dunk tank since it makes the punishment of getting dropped in that water all the worse!
