in the Year 2015

in the Year 2015 I broke the mental speed barrier by

I broke the mental speed barrier by

I broke the mental speed barrier by racing against a calculator for all

racing against a calculator for all

racing against a calculator for all those who don’t know what the metal

those who don’t know what the metal

those who don’t know what the metal speed barrier is a lot of people believe

speed barrier is a lot of people believe

speed barrier is a lot of people believe that a human brain can never be quicker

that a human brain can never be quicker

that a human brain can never be quicker than a calculator a human brain can

than a calculator a human brain can

than a calculator a human brain can never go quicker than a calculator

never go quicker than a calculator

never go quicker than a calculator because yeah probably whatever reason

because yeah probably whatever reason

because yeah probably whatever reason some people do believe that and the year

some people do believe that and the year

some people do believe that and the year 2015 I raced against a group of hundred

2015 I raced against a group of hundred

of racing against a calculator so the

of racing against a calculator so the volunteers who were here before want you

volunteers who were here before want you

volunteers who were here before want you guys to come here again and everyone in

guys to come here again and everyone in

guys to come here again and everyone in the crowd can open their calculators on

the crowd can open their calculators on

their phones and I’ll be telling you

their phones and I’ll be telling you what to do and I mean the same in my

what to do and I mean the same in my

what to do and I mean the same in my mind so you’ll know the difference

mind so you’ll know the difference

mind so you’ll know the difference between the speeds thing is that I’ll be

between the speeds thing is that I’ll be

between the speeds thing is that I’ll be taking a two digit number I’ll be adding
