Sherlock Holmes and DR. Watson went camping one time in Yosemite Park.
They were deep in the wilderness and all alone.
They set up camp, enjoyed a fine meal, and turned in late that night.
In the middle of the night, Holmes woke Watson and said,
"Watson, look up and tell me what you see. "
Watson looked up and said, " I see millions and millions of bright, brilliant stars."
Holmes said, "What does this mean to you?"
Watson pondered this and finally said, "Astronomically speaking, it means that in all those millions and millions of stars that there must be a world where intelligent life exists. Meteorologically speaking, it means that tomorrow it will be bright, clear, and beautiful weather. Watson then said,     "What does it mean to you Holmes?" Holmes said,               "Elementary my dear Watson. Someone has stolen our tent!!! "

Why were the teacher's eyes crossed?
Ans:    She couldn't control her pupils!!!

Watching his class taking a true-false test, a teacher notices a young man flipping a coin before writing each answer. "What are you doing?" he asks the student.
"Taking the test," the young man replies. "Heads is true and tails is false."
The period ends, and as the teacher collects the paper he sees the student frantically flipping the coin and staring at his exam paper. "And what are doing now?" asks the teacher.
"Checking my answers."

"Knock Knock."
"Who's there?"
"Opportunity."
"Can't be."
"Why not?"
"Opportunity knocks only once!"
