Riddle: A man comes across a sphinx who will eat him if he doesn't answer the riddle right. Here's the riddle.
In the morning of life I'm on four legs,
In the evening I'm on two,
And at night I'm on three,
What am I?
Answer: A Human.
MORNING OF LIFE
A baby that crawls on all fours
An adult that walks with ease
An old man with his trusty cane
