well, in TF2 i was playing spy in 2fort. i ran in the enemy's sewers and up into their base trying to kill a sentry that was blocking the main entrance. he had a level 3 sentry, dispenser, and teleporter (i dont know why he needed it, he was about 10 steps away from the spawn) I ran up to him, sapped his sentry, knifed him, then sapped his dispenser and teleport, cloaked and ran away. "WHAT THE FUCK, YOU CANT DO THAT YOU BLOODY CHEATER" i just laughed and kept playing.
*later on in the same match* I did exactly the same thing to all three of his buildings. "TOMBMAN YOU CANT DO THAT, FUCKING HACKER IM GOING TO KICK YOU" he started a vote kick, it failed. then someone started a vote kick against him, and he was gone in a few seconds. i lol'd pretty hard.
