Dave Grohl is here. Do you see him? He is all around you. He is everywhere. You cannot escape him. If you do not see Dave Grohl, you are obviously not a balanced human being. We must fix this. Give him what he wants. Give him anything and everything. Show him that you deserve to bask in the light of his perfection.
What will you give him? What do you give the man that has everything? You give him all of your possessions. Dave Grohl does not need all of your possessions. Dave Grohl does not need anything. He is perfect. He does not need to eat. He does not need to sleep. He can breathe underwater and he can fly to the moon and back in the time it would take you to blink just one of your eyes.
Dave Grohl simply needs to know that you are willing to give him these things. Repeat this line for as long as it takes: "Dave Grohl, greatest and most incredible of all, I offer up all of my earthly possessions to you so that I may bask in the light of your perfection."
Did it work? Do you now see him? You do. You have passed the test. You have accepted Dave Grohl into your life. You are now a better human being. Everything that you do from this moment on will be 1.5X more efficient than before.
Go, now, and spread the good word. Tell your neighbors. Tell your co-workers. Tell your friends and your classmates. Scream it into the atmosphere so that everyone will know the truth. You are free to finally start living.
