Crucifact Pun

The joke plays on the word 'crucifixion' by changing it to 'crucifact'. This suggests that if Jesus's crucifixion was a real historical fact, it would be called 'crucifact', which sounds like a humorous combination of 'crucifixion' and 'fact'. It uses wordplay to make a lighthearted comment about the historicity of the crucifixion.
