Possible Bug on Pirate Ryze joke

I was practicing Ryze in practice mode with a Ryze skin a friend gifted me a while ago (Pirate Ryze) and I did the 'Joke' command. It started like usual but then he got caught in a graphical loop. I allowed it to play out but after 3 minutes, it seemed unusual. I was stuck in this stance until I right clicked. Very minor, I know but still thought I'd report it.
