What is the Most "Bullshit" Tank Spawn?

The kinda spawn where you just go "guess we lose". My vote goes to the under the river section of The Passing, you drop down, probably surrounded by commons in an area with nothing but water that slows you down while a tank moves full speed to murder you.

It really feels like valve wanted you to just send some poor soul as a sacrificial pawn while the rest of you backtrack to a more suitable area to fight
