Basically Garlic posted a pic that was intended to be understood by old people only. But @moreinjuredthanowen liked the post which means that he understands it. Thus confirming that he posts and thinks like a much older person than he really is, which backs up the reason why many of us were shocked to find out that he was in his thirties and not his 60s.
If nobody else of a younger age has even seen the tribute shows when ronnie barker died fine... but I did and found it hilarious. I didn't see it when it first came out.
