This is something strange. I received a video attachment in this weeks newsletter of Unix.SE that is received every Tuesday.
The subject was 'Unix & Linux Weekly Newsletter - Tuesday, December 3, 2013' The video attached was [Why are Bad words bad] www.youtube.com/watch?v=Dd7dQh8u4Hc
Don't think Gmail added that ;). Didn't see any relevance with the video and unix.se newsletter. Have anyone else received it? Was it on purpose?
Update: Think that was not from the mail. But seeing it with the mail only with this newsletter.
