Isn’t this extremely offensive?

[Henrysmycat]

I was sent this. It’s in someone’s jacket on a flight to London. I find it extremely offensive, others thinks is tasteless.

Not remotely funny. Disrespectful, gross and disgusting. Standards have dropped to pond life level. I despair. I would not want my 9 year old granson seeing this. In private if this is your kind of humour, fine, but entirely not appropriate publicly

Extremely wishful thinking on his part.

More cheerfully, saw a post on FB today where a woman thought -4' warning in her car was a man having a poo..."
I don't get this one either but sound like it has the potential to actually be funny! Please explain

It took me a while to actually see the 'man' but the - sign is the seat, the 4 is his body leaned forward with his arms down by his his legs and then the degrees sign is his head.
