One time, playing Egyptian Ratscrew, a friend and myself both flipped a jack and slapped it. We couldn't agree who got the slap so we agreed to flip two more cards -- two more jacks. I slapped the jacks and got all four jacks in that one play. Anyway, I still lost that game...
It's actually Tien Len... not Lien. And yeah, it's a great game. Play a lot during holiday with family around and also through high school. The wikipedia page has a bunch of rules I've never heard in the 30 years I've played.
