Wise Doctor

A 90 years old man goes to Doctor Jim
and they had the following conversations;
.
OLD MAN: Doctor, my 28 years old wife
is pregnant, what's your opinion?"
.
DOCTOR JIM: Let me tell you a story;
A hunter in a hurry grabs an umbrella instead of his
hunting rifle. He moves into the jungle, sees a lion,
lifts the umbrella pulls the handle and...
BANG!!!
The lion drops dead!"
.
OLD MAN: (Exclaims) That's impossible!
Someone else must have shot the lion.
.
DOCTOR JIM: EXACTLY MY OPINION
