* The Korean store owner trying to explain what happened to the police.
-->'''Owner:''' The guy crazy. I told him "Take my money". He said no. He call me a thief.
* Foster walking into Whammy Burger (an ersatz [=McDonalds=]) and demanding breakfast. When the smarmy manager refuses (they stopped serving breakfasts just 3 minutes ago and clearly had plenty of ready breakfasts sitting on the warmer), he pulls out a TEC-9 and holds the place up then begins calmly demanding a breakfast while chatting with the patrons. At one point he accidentally discharges it into the ceiling and has to calm everyone down by telling he didn't intend to do that.
-->'''Foster''': It's alright! It's an accident! [[FalseReassurance It's a sensitive trigger!]]
** Foster calmly walking around the diner clutching a TEC-9 and asking people how they're enjoying their lunch while everyone is frozen and convinced he's about to kill someone is NightmareFuel, but it also CrossesTheLineTwice so hard that it's hilarious.
---> '''Foster:''' Enjoying your meal? ''[to a young boy]'' How 'bout you, son? Is it good? ''[to a woman]'' And you, ma'am? How's the food?\\
'''Woman:''' [''[[VomitIndiscretionShot stress-vomits]]'']\\
'''Foster:''' [[ComicallyMissingThePoint Looks like we have a critic]]!
** The old guy who sees Foster produce a machine-gun from a bag and ''immediately'' abandons his terrified wife to make for the front door, leaving her to be a hostage. Foster catches him, berates him and makes him sit back down with her.
** [[InLoveWithYourCarnage The flirtatous gaze Sheila (the counter girl) gives to Foster throughout the scene.]] She knows the restaurant's policy is bullshit.
** The little black kid who sheepishly raises his hand when Foster berates the staff for having such sad-looking burgers and asks "Can anybody tell me what is wrong in this picture?"
** And the absolute funniest detail about the scene? After scaring the shit out of everybody there, Foster just changes his mind in the end and goes for a burger and fries instead.
* Foster's mishandling of a rocket launcher.
** To add on to that, a kid teaches him how to use it, pointing out that he saw one being used on TV.
* Before the rocket launcher scene, Foster walks past a douche yelling at people while stuck in traffic. Foster deservedly ''[[MegatonPunch punches him out cold]]'' and continues on his merry way. For added funny, the man is [[CreatorCameo played by the film’s writer, Ebbe Roe Smith.]]
* "Hey, you forgot the briefcase! YOU FORGOT THE BRIEFCASE!!"
* Foster shooting up a pay phone after use because an angry man yells at him to hurry up and get off.
* Though the character is creepy and undoubtably malicious, the [[spoiler: Neo Nazi]] gun store owner is pretty funny just by how over-the-top racist and homophobic he is. Every line he says is said with such perfect [[LargeHam ham]].
--> "FAGGOT SHEEYIT!"
* Foster firing a shotgun at an old man's golf cart when he tries to hit him with a golf ball, causing him to have a heart attack and the golf cart to malfunction and speed off into a water hazard. As the cart rolls into the hazard, the old man begs for his pills, which are in the golf cart.
--> '''Foster:''' Bad news. Your little cart's gonna drown. And now you're gonna die wearing that stupid little hat! How does it feel?
* The guy who pesters Foster for money in the park who claims he hasn't eaten in three days - except for the ''sandwich he is currently eating.'' He also claims he was in 'Nam despite being about 30, makes up a story about a car when he doesn't have one, much less a license to drive one, and is just a terrible liar all around and a pushy asshole. Foster calling him out on every single lie and denying him any help is just deliciously satisfying.
* The doodle on the Hawaiian tropic Billboard of the head sticking out of a bikini saying "help"
** Seen again later by Prendergast, who [[ActuallyPrettyFunny can't help but pop a big grin seeing it]].
