This is not meant to offend. Sam Is NOT Doing Blackface, he is just simulating the Eddie phone blowing up and the debris coming off it. I support #BlackLivesMatter more than anyone so please don't take this clip the wrong way.
No one would rationally would take this as offensive, Unfortunately you have a lot of low-life attention seekers wanting their 15 minutes of fame dobbing funny skits like this in to the media. That's offending in itself. Keep uploading segments like this Chris!!
I know this is just a skit, but new ABC footage of the 1979 Grand Final with a slightly different angle, confirms the ball was inside of play when Harmes tapped it in.
