Where you never told as a child that something is only funny once? Rick rolling got boring the second time somebdy did it, AGES AGO. Now the zsecond time in this thread it's even duller still.
It's a pre-formatted off the shelf joke for people who lack the creative spark and imagination to shoot a line off the cuff. It is: Dull; unimaginative; and about as humerous as the Queens speach/State of the Union address.
I recommend you do some drugs to encourage your imagination, and the experience of laughing at nothing will probably fit in well with you too.
