A Scottish lad takes out the local sweetie on a walk across the hills. As they admire the view he says to her, "Why don't you take a peek under my kilt?"

She says, "No, no, I couldn't do that."

"Please?"

"Well, all right." She lifts his kilt and cries out, "Ach, it's gruesome!"

He says, "Lift it again, it just grew some more."
