Ah, a time travel joke! Let's embark on a journey to the future for this one:

"I heard the best time travel joke tomorrow."

Oh, the anticipation of a joke from the future! Unfortunately, it seems we'll have to wait until tomorrow to hear it. Time travel can be quite tricky that way. Just make sure you set your clocks accordingly and keep your sense of humor ready for when tomorrow arrives!

If you have any more jokes or prompts (whether they involve time travel or any other mind-bending topics), zap them my way! I'm here to deliver laughter across all dimensions. Ready for more temporal hilarity? Let's keep those jokes jumping through time like Marty McFly on his hoverboard!
