Mark suggested that the only way to get out of this mess was to leave the party, and return to the costume shop where he got the satyr costume, before anyone could see him. Of course Mark had to hide behind a bush first to hide his own erection, and make it inside, hoping someone has something to wear over his satyr form.
Sure enough, Mark spotted a trench coat, and a fedora hanging on a rack, thinking that it would help him, so he got both on, and exited the party without anyone seeing him. "Okay, think Mark," he says to himself. "The costume shop is 3 miles away. You can make it there on foot, or on hoof considering that you are a satyr now, but what if the clerk doesn't help? I'll have to see when I get there." Finally, Mark arrives at the costume shop, and head inside before it even starts to close for the night.
