Hulk of a Different Color - S2-E1
Character mistake: When She-Hulk is objecting to the prosecution using live footage of the Rick Jones-Hulk hybrid to prove that Bruce Banner is not the Hulk, the judge overrules her without letting her state the legal grounds to her objection.
Character mistake: When the woman is looking at the high school photo of She-Hulk at the high school reunion, she says "Oh, look. Remember her? Jennifer something or other." You can see that her full name is written directly underneath the photo, so there's no reason why the woman would look at the photo and not know what Jennifer's last name is.
Answer: The Hulk is a giant brute who smashes everything in his path when he is angry. In Ang Lee's "Hulk," General Ross, played by Sam Elliot, explains it to his daughter.
