The memorial plaque for John Venn (1834 – 1923) in Drypool, Hull, England, contains a mysterious phrase:
John Venn is, of course, a mathematician who proposed Venn diagrams, this bit is easy. But the phrase
Really strong beard game
is more interesting. “Really strong X game” can be found in print media and on the Internet for some other value of X as well. It means that something is impressively done (or, by extension/humor, impressive).

Secondly, a quote from Wikipedia:
He built rare machines. A certain machine was meant to bowl cricket balls. The machine was so fascinating that when Australian cricketers were visiting Cambridge, the machines were used to entertain their arrival. The bowl cricket ball machine that Venn built actually bowled out the top ranked player of the team four times consecutively.
