Looked in the catalogue, didn't see one, so let's share shit you've had to endure from battling/trading with people online. This just happened to me;

>Profile shout-out is 'LF: Regigigas'
>Get a trade offer, accept that shit
>He shows up a Regigigas, sweet, now's my moment
>As I'm dragging through my boxes, I accidentally land on my Shaymin and and show it to him
>Didn't mean to, so retract the Shaymin and offer something I'm willing to give (Entei)
>he retracts the Regi
>offer a Raikou, a shiny Suicune, all three of the Lake Pixie trio
>The other player no longer wants to trade
>Trade ends, I send him a 'Nice!' and go on my business
>five minutes later, he sends me another trade request
>flashes a Flabebe called 'IWANTSHAYMIN', then offers the Regigigas
>end trade immediately

Fuck off am I giving you an event legendary for something I could get on the GTS with a bit of patience, dude. At least offer something fair in return.
