Dog Dance Lessons
This guy decides he wants his dog to be able to dance, so he enrolls the pet in dance classes. Dutifully, he takes this dog to class every week, but he sees no improvement. Finally, he takes the instructor aside and says, "I'm spending a fortune here. Why isn't my dog's dancing improving?"
"I'm sorry," the instructor replies, "but there's not much I can do. Your dog has two left feet."
