"Fastest Thing" joke

Four Guys, From Harvard, Yale, Mit And Santa Singh From Punjab University Were To Be Interviewed For A Prestigious Job. One Common Question Was Asked To All 4 Of Them.

Interviewer: Which Is The Fastest Thing In The World?
1. Yale Guy: Its Light, Nothing Can Travel Faster Than Light.
2. Harvard Guy: It's The Thought; b'cos Thought Is So Fast It Comes Instantly In Your Mind.
3. Mit Guy: Its Blink, You Can Blink And Its Hard To Realize You Blinked
4. Santa Singh: Its Loose Motion
Interviewer: (Shocked To Hear Santa's Reply, Asked) "Why"?
Santa Singh: Last Night After Dinner, I Was Lying In My Bed And I Got The Worst Stomach Cramps, And Before I Could Think, Blink, Or Turn On The Lights, It Was Over!!!!

The Interviewer Then Told Santa Singh To Wear Red Coloured Shorts During Such Situations.

Santa Was Confused; He Asked "Red Shorts? ?? How Does It Help"

The Interviewer Told "Dont You Know Red Signal Stops All Traffic, Howsoever Fast It Is??????????????"
