A funny one is that there was so much objection to General Relativity that they compromised by giving Einstein a Nobel for his work on quantum mechanics.
His acceptance speech was about general relativity.
I recently watched this quite video on the subject: https://youtu.be/zS7sJJB7BUI?feature=shared and found it quite enjoyable.
