I was wondering why the frisbee was getting bigger, then it hit me.
Why this joke works
Watch the Frisbee Approach
Start with genuine curiosity, as though the growing disc is a strange problem you are still solving. The audience can picture it moving closer even if the speaker cannot. Pause after “getting bigger,” then let “it hit me” carry both meanings at once: the answer became clear, and the frisbee arrived physically. Keep the impact cartoon-light rather than acting injured. The line works especially well outdoors, where a passing frisbee can supply the picture before the punchline does.
A closer look
A Quiet Observation Turns Into Sudden Impact
The first clause invites a visual explanation: an approaching disc naturally occupies more of the observer’s view. “Then it hit me” resolves that mystery twice, as both a realization and a collision. The sentence’s comma creates just enough delay for listeners to picture the growing circle before the physical interpretation lands. The narrator’s unusually calm curiosity makes the avoidable accident even more playful.
Fact behind the joke
Frisbee Is a Brand Name for a Flying Disc
A USPTO case record identifies FRISBEE as a federally registered Wham-O trademark used for toy flying discs. It states that Wham-O introduced its Frisbee flying disc to the public in 1957 and distinguishes the branded name from the generic term “flying disc.” The joke uses the familiar brand name, while the object’s apparent growth simply signals that it is rapidly getting closer.
