Although Lincoln speaks to the viewing audience in most episodes, characters in bold have been observed doing so as well while others look at the fourth wall, not speaking to the audience, but breaking the fourth wall nonetheless.

Lori finds out Leni is wearing one of her shirts, and angrily demands her to take it off. Leni responds she can't, as there are boys present. The only "boy" present is Mr. Coconuts, who raises its eyebrows causing Luan to cover its eyes.
Lynn Sr. talks about getting rid of "the one with the white hair" which he doesn't even know if it's his. He's actually talking about a tie that's designed like a rabbit (hare), but Lincoln thinks he's talking about him.
"Butterfly Effect" - Luna was about to say that the family is on a highway to hell, but before she said "hell", she got interrupted, and said "hello" instead.
"Two Boys and a Baby" - The scene where Lily's dirty diaper is flung into the ceiling fan is a subtle visual pun on the phrase "sh*t hits the fan".
"A Novel Idea" - Lincoln: "I can see Uranus from here, and boy, is it gassy."
"11 Louds a Leapin'" - During the third song Luna was singing, she was about to say "p***ed".
"Suite and Sour" - The Louds were actually kicked out of the resort due to Rita and Lynn Sr. skinny dipping in the pool. However, it is implied that they did much more than skinny dip.
"Back in Black" - Lincoln: Did you bring Uranus?, Rusty: Never leave home without it.
"Lock 'N' Loud" - When Lucy imagines the burglar stealing her bust of Edwin, the burglar is shown turning the bust around before stealing it. The way the burglar does this resembles someone snapping someone else's neck.
When Lincoln and Clyde were viewing the footage from the dog, Bobby is seen taking off his pants, and Clyde quickly shielded his eyes. The way this scene plays out is that Clyde was given the implication that he was watching an erotic film.
In addition, Pam's line, "Why don't you slip out of those clothes and we'll get started!" implies that something inappropriate will occur.
Lincoln and Clyde watch as Bobby goes with different girls, then with an older woman, with a dog, and then with a man; thus implying they thought Bobby was a gerontophile (sexual preference for the elderly), a zoophile (sexual preference for animals), and a homosexual (sexual preference for the same gender).
"Frog Wild" - When one of the classmates asks what two of the frogs are doing, Mrs. Johnson quickly covers them with a map of the United States, which implies they were doing something really inappropriate.
"Job Insecurity" - Mr. Grouse: "Now, if you'll excuse me, I have a date with two hot dishes..." [the siblings become disgusted] "...of lasagna, for Pete's sake!"
"Change of Heart" - When Lola heard Lori talking to herself in the bathroom, Lola, who was horrified at what she heard, remarks "I don't think I need to tinkle after all.", which seems to imply that she wet herself.
"Health Kicked" - Lori and Leni witnessed their father's skinny jeans slip off, they quickly shielded their eyes in disgust, giving the implication that they were exposed to his private areas.
