Groaner joke... amirite?

A man is hiking through the Welsh mountains...

A man is hiking through the Welsh mountains with his pet newt when he comes across a pub. He enters the pub and sees that there is a sign that says dogs are allowed in.

"Can I bring my pet newt inside?" The man asks the bartender.

"Hmm, I suppose so." The bartender says, slightly sceptical.

The man leaves and enters again with the biggest newt the bartender had ever seen. It was almost a meter long and the bartender was shocked silent.

"This is my newt: Tiny." The man tells the bartender.

"Tiny? But it's massive!" The bartender says in shock.

"He's called Tiny because he's my newt."
