Fool's Mate Analysis.

So I was messing around with Analysis and I decided to input Fool's mate. I noticed that after 2.g4 on the evaluation bar, rather than indicating M1 as would be the case usually, it reads as -318. I thought this must be some sort of cheeky reference and I was wondering if anyone had any insight as to what this might mean? Thanks in advance!

The reason the eval bar shows 318 is because it is a reference to March 18th in China, the current day I am writing this.

Can you tell me what remarks it gives you on each move on Fool's Mate? I just defeated my opponent using that and I want to see what my remarks on the Analysis are. I will have a go on the Analysis.
