Jon: Shut the fuck up Jen, you phony materialistic slut. Jan's actually intelligent, you're just treating him like a child, ironically making you the retard in this situation.

2) You fucking retard, you don't put the cheese in the boiling water you strain the pasta first. This is the last time I'm letting you make the mac and cheese.

Any person who's mental deficiency has lowered his IQ to 70 or less. Retarded people usually have a very limited vocabulary and often times have trouble understanding reason or logic especially if the person speaking to the retard has an above average intelligence. Retards who's intellect has been severely impared sometimes make unnatural or spontaneous motions with their limbs which make other people uncomfortable. Speech may also be affected by mental retardation causing constant stuttering and mispronunciation of easy words. Retards can be considered by some as almost "inhuman." This is due to the fact that retards can not understand basic philosophy and have no perception of things they haven't physically experienced themselves such as the atom or the concept of infinity. Mentally retarded people should not be brought to public places like churches or public performances where much like babies, they can cause a disturbance due to noise.
