Funny / What About Bob?

• Leo's Evil Laugh after he has Bob committed, especially since it's easy to see that his smugness is about to be crushed. He gives off an even more hilarious one after he straps a time bomb to Bob and runs off. Given the level of slapstick humor in the film (with Leo being the unfortunate target), you'd almost expect him to run into a tree branch or fall over or something.
  Bob: You'll take care of Gill for me?
  Leo: Yeah! Don't worry! I'll feed him 'til he's big and fat, and then I'll eat him, Bob!
• Not long after, while Leo is gloating over having "finally" gotten rid of Bob:
  Leo: On Tuesday, we'll eat Gill. On Wednesday, we'll eat Bob. (laughs, Beat) No no no, that's going too far.
• The Angrish way that Leo tells Bob to get out of his car. About the closest it can be reproduced in print is "GEDOWDADAKA!"
• When Leo tells Bob to express himself during their first session, the latter lets loose a stream of curse words, with Leo's secretary listening with a nonplussed look on her face. One wonders if if it happens often or if she feels the same way...
• On the day of his interview, Leo tries to wake Bob up and get him to leave, but his increasingly loud and physical attempts to awaken Bob fail miserably. Then the alarm clock goes off, and Bob shoots right up.
• "I feel good. I feel great. I feel wonderful!"
• The mental hospital scene where Bob tells jokes to other patients and staff members was already funny, but it becomes downright hilarious when you realize that the entire scene was ad-libbed by Bill Murray. In the same scene, when Dr. Tomsky tells Leo that they have no reason to keep Bob there:
  Dr. Tomsky: Relax, Leo!
  Leo: I'm relaxed!
  Dr. Tomsky: Take a vacation.
  Leo: I'M ON VACATION!!!!
• Leo's hammy temper tantrum after Bob ruins his interview by stealing the spotlight, and Sigmund's (Leo's son) rebuke for throwing Bob out of the house:
  Leo: You think he's gone? He's not gone! That's the whole point! HE'S NEVER GONE!
  (Opens the door to show Bob standing right there)
  Bob: Is this some radical new therapy?
  Leo: YOU SEE?!
• How the Guttmans greet Leo:
  Mr. Guttman: Hello, Doctor Marvin! The house looks good!^note The Guttmans were originally going to buy the summer house that Leo bought. The Guttmans say to Bob that they "worked a lifetime" to save up for a down payment for the house, until Leo "swooped down with his bag full of money, and grabbed it up from under us!" The Guttmans have held a grudge against Leo ever since.
  Mrs. Guttman: Burn in Hell, Doctor Marvin!
• "Roses are red, violets are blue. I'm a schizophrenic... and so am I."
• At dinner, Bob constantly pesters Leo with his "Mmmm.... Mmmmmm...." until Leo finally explodes shouting "WILL YOU STOP THAT, PLEASE?!"
• Dr. Marvin explains to Bob as he ties him to a tree:
  Dr. Marvin: This is called black powder, Bob. One teaspoon of this stuff can blow up a tree stump! (hangs a canister around Bob's neck) Here we go!
  Bob: And how much is this?
  Dr. Marvin: Twenty pounds worth! Hahahahahaha!!
  • This, of course, literally blows up in Dr. Marvin's face when Bob leaves said twenty pounds of black-powder in his holiday-house and turns it into an orange fireball.
