A little math fun this time: There are several interesting ways to get to 77:
  • The obvious one makes it a bi-prime: 7*11=77
  • It's also the sum of the first eight primes: 2+3+5+7+11+13+17+19=77
  • And it's the sum of three squares: 4^2+5^2+6^2=77
And of course, containing the same digit twice, it's also a "schnapszahl" (lit. "liquor number", a German tradition), which further justifies a little dram (as if I didn't have enough reasons to have one).
