The kids were cracking up laughing at the clothes Mom bought
And those who weren't laughing still had a ball
Because they were pointing and whispering
As I walked down the hall
I got home and told my Mom how my day went
She said, "If they were laughing you don't need them,
"Cause they're not good friends"
To me the launch of the Backstreet Boys Larger than Life intro the actual song opens with omnious laughter (almost the same as Feel Good Inc noted earlier). This is at 1:05 in the video
