ERS
I love that there’s a quite-detailed Wikipedia entry on Egyptian Rat Screw. I was definitely reminded of this after reading about the Granades teaching Eli to play Slapjack. I learned ERS at Space Camp years ago, and I love to play it at lock-ins to while away three hours without really noticing.
If you had “Geof is posting this generally useless entry because he’s in a soul-sucking teleconference regarding a duty that takes up 3% of his time because he’s trying to do most anything to stay awake” in the “Why is this IJSM entry being posted?” pool, you win a cookie! I shall now implore you to shove the cookie down my windpipe so that I can end my suffering. [Goodness, I'd rather Blogathon again today than be doing this right now.]
