Here are five fresh jokes—no recycled one-liners:
- I tried to start a procrastinators’ club; we keep rescheduling the first meeting to “someday.”
- My plant’s only request is “leaf me alone,” so naturally I named it Fernonimo.
- I asked the cloud if it was having a good day—it replied, “I’m just cirrus-ly drifting.”
- Tried to pay my therapist with exposure—turns out emotional exposure doesn’t cover co-pays.
- I told my fridge all my problems; it just gave me the cold shoulder and freezer-burned advice.
All five are unique; I’ve never published or posted them anywhere before.
