Fastest Intro Bot Game in League of Legends?

Some of my friends and I got together to play some intro bots, and decided to rush mid. We wanted to set the world record, sooooo. yeah. We got 5:26. There's no way to post a screenshot but it happened. We don't know if it is a world record, but it was super fun.

We played Tristana, Warwic, Master Yi, Xin Zhou, and Jinx. We proxied the first enemy wave the killed the first tower off the first wave, we carried that push with the second and had the inhibitor at 3:26 and the nexus was destroyed at 5:26.

If you beat this, please tell me. I am curious to know how.
