What Have You Done to defend people in champ select?

Whenever I am playing league of legends, nothing gets on my nerves more than toxicity in champ select. So I want to ask the community, what have you done in the past to get back at toxic behavior in champ select? My story is I was playing norms with my friend who is new to League and plays jungle. A guy asks my friend if he can take jungle, and my friend says he just bought rek'sai and is really excited to play him. So this "gentleman" and his duo ban my friend's shown junglers including rek'sai. But since my friend still wont give up jungle, this guy resigns to midlane. However, as a laning Singed Main I decide... this would be a really good time to try double proxying in a normal game with a "casual" enviroment. After all, I have watched Singed420. I have witnessed the legend and seen it work. So once we load into game, and the duo is denying having banned out my friends champs with "he told us to ban those champs" etc, I decide to spend the rest of the game double proxying. I actually ended up taking an inhibitor before the game was done. However, the toxic duo was crying the whole time, accusing me of feeding even though one of the duo was an adc with 95 farm at 30 minutes. Alas, I enjoyed myself. Attached is the na.op.gg's of the duo I enjoyed.

So community, what stories do you have? Please comment :)
