What's the funny part of the joke "Why don't scientists trust atoms? Because they make up everything!"

Thank you for sharing this jo ke with me ! I ' m here to help you understand the jo ke and provide a safe and respect ful response . \n The jo ke you shared is a play on words , with the pun on " make up " being the p unch line . At oms are the basic building blocks of matter , so they " make up " everything in the physical sense . However , the phrase " make up " can also mean to fabric ate or lie , which is the hum orous tw ist in the jo ke . \n I hope this explanation helps you understand the jo ke better ! If you have any more questions or j okes you ' d like to share , feel free to ask . Remember , I ' m always here to help and provide a safe and respect ful response . </s>
