Rick: A hair, Morty, I need one of your hairs! This isn't Game Of Thrones.

Rick: Alright, Morty, whoever you smear this stuff on will fall in love with you, and only you, forever. Ya happy now, Morty?

Rick: Www.. what am I, a hack?! Go nuts, Morty, it's full proof.
Rick: Ugh, unless she has the flu.
