Well, the trick is to change the subject so that it is no longer political
This joke was originally about politicians:
When Bill Gates, Bezos, Zuckerberg, and Steve Jobs died and before the Pearly Gates, God made them do a test before they could enter. He said, "in front of you is a pit full of sh*t. If you can walk on top of the sh*t, you can enter Heaven".
Bill Gates went first and he sank to his knees in sh*t. He went straight to Hell.
Bezos tried next and he sank to his waist in sh*t. He went straight to Hell.
Zuckerberg tried next. He almost drowned in sh*t. He went straight to Hell.
Steve Jobs stepped into the pit. To everyone's amazement, he did not sink. He walked on the sh*t! When he got to the other side, Ive and Cook emerged from the pit, covered in sh*t, holding him up.
That joke can be swapped around to include any politician you like (or dislike)
It may not work if the joke depends on Trump's orange skin or Boris Johnson's hair but you get the idea ...
