Sanity test

I had seen this before.

I am usually a pretty humorous person - but for some reason, I just didn't laugh at this.

What the hell is wrong with me?:confused:
 
I must have stared at that for a good.... 7-8 minutes (cranked up the volume after a few secs, then waited for the audio file to loop). I didn't even crack a smile...... what is wrong with me?:confused:.

.....:cry:
 
I didn't laugh but i started smiling after 1.5 seconds does that make me insane or just slightly crazy?
