Fast

Four guys, one each from Harvard, Yale, MIT University 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?

Yale guy: It's light, Nothing can travel faster than light

HARVARD Guy: It's Thought, because thought is so fast it comes instantly in your mind.

MIT guy: It’s Blink, you can blink and it’s hard to realize you blinked

Santa Singh: It’s 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 !!!
