What happened to the egg after it went on the rollercoaster?
It was scrambled.
Alright, listen up, buttercup. The joke is that the egg went on a rollercoaster. After a ride on the rollercoaster, the egg was "scrambled". This is funny because "scrambled" has two meanings. The first is that the egg was shaken up. The second is that it was cooked into scrambled eggs! Ha! Dumbass.
