Dad Joke

Two guys are walking through a forest when they come across a huge hole. 'Wow, that looks deep,' says one. 'Let's throw a rock in to see how deep it is.' They throw a rock and wait... nothing. 'Let's throw something bigger.' They find a log and heave it in. Still nothing. Then they spot an old transmission from a car. They pick it up and throw it in. Suddenly a goat comes running through the woods and leaps into the hole. A farmer walks up and asks, 'Have you seen my goat?' 'Yeah, it just ran past and jumped in this hole!' 'That's impossible,' says the farmer. 'I had him tied to an old transmission.'
