Once, one of the comics revealed Nate's weight to be 86 pounds. However, more comics supported Nate being 87.
He also gained 5 pounds by eating too much fried dough.
He broke his right wrist twice, once while playing football in 1992, and another time when he dived off of a table at Jefferson.
He was once sick, and Ellen made him watch and take notes of her favorite TV show, so she could know what happened after she got home. Nate did that, but in the end, he wrote that the main character had been killed (which he hadn't), which made Ellen scream.
He has Ailurophobia, which means he is afraid of cats.
