Endoplasmic Reticulum 

-Tedious biology term, used in public education to stimulate teen suicide rates for the entertainment of teachers.
-A complex, rediculous compound word that causes the eyes to bleed at the sight
-I HATE AP BIOLOGY!!

"students, now moving on the the outer part of the cell: the Endoplasmic Reticulum, and the G---"

*BLAM, BLAM*

Ectoplasmic Reticulum 

This is the organelle in cells that is responsible for cum (also known as ectoplasm). This organelle converts glucose to sperm, resulting in cum.

Dude, I think your ectoplasmic Reticulum went off too many times in bed last night.

A micro-sized ribosome attachment to the smooth endoplasmic reticulum. Often seen in animal cells.

I found my ultramicroscopic-endoplasmicreticulum!
