Why walk or run when you could slither or crawl
Why overthink your woes when you've hit the wall
What's holding you back, you got nothing to lose
The primitive man, well you know they never had those blues

Turn on your reptile brain

Have you got the smarts to get so super dumb
Lose inhibitions, dismiss higher functions
They may call you unevolved, well you got nothing to prove
Let your instincts shake you back into primordial ooze

Turn on your reptile brain
