Share an Amusing MtG Story

This thread is planned to share something funny about your time playing MtG.  All I ask is that you refrain from demonizing other players, but having said that almost everything humourous is based upon miscommunication so...

Feel free to share anything from the World Series player who was obsessed with a working Earthbind / Flight combo deck to the time you lost in an Extended tournament on the second turn to a kid with a Tireless Tribe and About Face just because you weren't smart enough to block it.

The funny story I wish to start with occurred last year.

I found myself in a community of young men who were primarily avid Yu-Gi-Oh players. Always being up for any sort of board or card game I was willing to play as long as someone would teach me.  They elected to send me to the most experience player.  This gentleman taught me the basics of play and let me borrow a deck for the duration of the week.  Upon discussions over the gaming table I found that he had begun to start playing MtG. Given my background I offered to look at his decks if he wanted pointers.  Bear in mind this is a very cautious and savvy player & trader who had already pointed out the need to obey the Yu-Gi-Oh version of a banned restricted list to the rest of this small community.  He had a decent Modern & Standard MtG deck and felt that he was in the process of developing a decent Legacy deck he was just looking for the last three cards to make it work.  When I looked at his Legacy deck I was surprised he had combined the Candelabra of Tawnos (the card he was looking for he had found a Poor-Very Poor quality one for cheap) with Wild Growth and Fertile Ground to create an infinite mana loop.  I immediately knew he had a problem (switch between the Antiquities & online version of the card to understand what he thought and the problem), as I have often seen players who didn't know about the Mono & Poly Artifact rules.  Fortunately I had caught the mistake before he spent extremely large amounts of money on the cards in question.  One of the most amusing things to me is that the game has gained such a stability that such an error could occur to a seasoned player, but then I still remember taking counters to tournaments in order to play Time Vault.

Go ahead and share.
