Here are 5 jokes:
- Why don't skeletons fight each other? They don't have the guts.
- I would tell you a joke about time travel, but you didn't like it.
- What do you call a fake noodle? An impasta.
- Why did the bicycle fall over? It was two-tired.
- I used to play piano by ear, but now I use my hands.
5 are unique (all are distinct from one another).
Note: If "unique" means completely original and never told before, the answer is likely 0, as these follow common joke patterns. But within this set of five, none are duplicates.
