Had a pear landed on his head all might have been different. However, this was unlikely. Pears are not entrusted with holding mankind to the ground. But apples are. Yes, they are.
Apples ARE gravity.
Ah, because at any one moment there are more apples and the remains of apples on earth's ground than on trees. So everything, including other apples, is attracted to the ground. There are only a few apples on the moon, which is why you can bounce around on it like a prick. Jupiter, on the other hand, is crammed full of apples, and mainly strong varieties like Orange Pippins at that. The gravitational pull on Jupiter is so strong it beggars belief.
