Randall

Randall is shown to be extremely gruff. He constantly insults others without really trying, especially when they disagree with him in some way. He seems to dislike everyone Mark meets, especially Callie, though the two do grow fond of each other after a brutal fight. This turns out to be a common interaction between him and others, where upon meeting someone he may be rude, but in another episode he will be seen working with that person. Another example of this is Leonard, who in season 2 he is working on another scheme with to make money.

He has some ridiculously narcissistic traits, as he considers himself an "unstoppable mangod." He also has some rather creepy and disgusting characteristics, such as a tendency towards younger women and repeatedly molesting his roommate Mark Lilly.

She has admitted that she has been living her sex life for so long that she makes no distinctions when it comes to choosing her sexual partners, on one occasion a toaster. She also has a bad habit of using Mark's things without permission.
