Mongolian gerbil poop

Hoy he recibido este email de una lista de correos de la universidad (es en serio, no he cambiado ni una coma):

Subject: [BIO] Mongolian gerbil poop

Yep, I have reached a new high in my scientific career, begging for poop. 

I just need a fresh pellet of an uninfected Taconic Mongolian gerbil for some 

microbiota work I'm doing. That would be awesome if you could give me crap.
