Brick Joke/Newspaper Comics

• The most famous, and notorious, is Krazy Kat whose running gag was having Ignatz the Mouse literally throw a brick at the head of the title character. In nearly every episode.
• On one occasion, Garfield kicks Odie into next week. The following Monday, Odie falls onto him.
• In a FoxTrot story arc- in which Summer camp pal Phoebe and her brother Eugene revisit the strip- Phoebe uses this trope in lieu of explanation for how she knew it had been her brother who had stolen their camp journal: "Introduced, and then forgotten! How could we have missed that?!"
• In For Better or For Worse, a doll is flushed down the toilet. Years later; literally years later, it's pulled out of the pipes.
• Mark Leiknes' Cow And Boy has enough running brick jokes for a whole wall. Casual readers must be bewildered by the cat-copters, bazooka-toting orcas, and cardboard cutout stand-ins of the boy.

• Once in Garfield, Garfield kicked Odie into next week for eating his food. Odie was absent in the strip for the remaining two days of the week (and in the Saturday strip, Garfield comments that "Lunch isn't the same without Odie"). Sure enough, on the Monday of the next week, Odie came crashing down into the strip. Onto Garfield.
• In Pearls Before Swine's Ten-Minute Retirement, Stephen Pastis was sent to court and sentenced for life, because Rat advocated the overthrowing of the government. He convinced the judge to run one more Croc Story Arc. Said arc was about Zebra building a wall to keep the Crocs out, and eventually they strap tons of dynamite to a Croc named "Melvin", but he goes in the bathroom to read the newspaper and do the crossword. So, to keep their house from blowing up, two Crocs drag him out of the house, and launch him a great distance with Junior's see-saw. Where did he land? The courthouse Pastis was in. The dynamite then exploded, blowing it to smithereens and freeing Pastis.
  • There was a short arc at the very end of 2003 where Pig teaches his army men toys to be Oprah-loving hippies, much to Rat's annoyance. It heavily influenced the Viking characters that would appear a few years later. 3 years later, there was a strip where Rat gets a bunch of girl magazines in the mail, and says they had better not be for The Vikings. He then enters the house to see that Pig is reading a magazine about guns with them. Rat says "Uhhh...Nevermind." and leaves. After a Beat Panel, we see that the same army men are next to him, with one saying "If that Cosmo's not here today, I will just SCREAM."
• In an old Baby Blues strip, Wanda thinks she should wean Hammie off of the pacifier because she read a magazine article that says babies could become too attached to it. In a recent strip, Zoe learns that Hammie still sucks his pacifier in secret, at six years old.
• In For Better or For Worse, Mike bought a doll named Naked Ned at a yard sale, thinking it an interesting curio. During college, he kept the doll suction-cupped to his dorm window; when he graduated, Mike and his roommate, Weed, argue over who gets to keep the doll. After Mike has retrieved the doll from Weed's girlfriend, it is flushed down the toilet. Years later, it's removed from the pipes.
• The January 15, 2012 Brevity featured a pair of kids stepping out of a box. The boy points at something, and says "It worked!". Many readers were perplexed, others thought it to be a reference to the 2011 Doctor Who Christmas special. Come January 22... The same pair stand in front of the closed box, which reads 'Time Machine'...on the 15th, he'd been pointing at the strip's date.
• Bloom County once had a string of 4 strips where Opus repeatedly called 911 for non-emergency purposes like "There's a 465-pound woman across the street pruning her azaleas wearing pea-soup-green hot pants!!" Five days later, Steve Dallas was abducted by aliens, and the punchline to the scene was Opus calling 911 and their immediately hanging up.
