I come in peace to your planet from a long way off in a solar system not unlike yours in the andromeda galaxy as you would call it. I visit Earth because I find it's inhabitants most fascinating. On my planet you don't need weed because we recieve a constant supply of the thc related molecules on a constant basis but I still smoke the good herb because I enjoy the flavor and aroma.
I love tacos! Damn now you got me hungry. Earth makes the best tacos in the Milky Way Galaxy. You want better tacos you have to travel many billion lightyears to a galaxy where all they eat is mexican food and sometimes I'm just not in the mood for intergalactic travel just to satisfy my munchies.
