Michael and Timothy had just left the Pub and decided to take a shortcut through O'Leary's farm when they chanced upon O'Leary's prized stallion. Promptly, Timothy raised it's tail, took a quick swipe then applied it to his lips.
Michael, dumbfounded, asked:
"Is horse manure good for chapped lips?"
Timothy replied:
"I don't know, but it sure keeps me from lickin' em!"
