Hmm...let's see...
It was happen few years ago, when there were only Base Set and Jungle...
six of us (me, my older and younger bro, my cousin, his younger sister, and his younger bro) bought a Base Set booster pack from a Toy Store. The one who chose the Venusaur pack is me and my little bro, the rest chose Charizard and Blastoise one. Then we going to pay it up. After that, we want to pull the cards right away, so I chose one of 2 Venusaur. But, when I want to chose one, my little brother insist that the one I chose was his. Well, I don't mind that... so I give the one that I chose to him and I just get the other one...we began to open the pack... Damn! I got no holo, only useless Clefairy Doll! But my little brother got Venusaur Holo from the booster that I chose before! Arghk... Only if I didn't give it to him...
The other funny part was, my cousin's younger brother got 12 cards from his pack instead of 11! I remember that he got Dugtrio and Dragonair there! Lucky him...
