Two L4D2 moments here:
1) I was playing with my cousin on expert, Dead centre, we had just gotten past the bit where you clear the dumpster. everyone else was on low health, I had yellow. I whip out my katana, take some adrenaline, and run into the next room to scout it out. I run head first into a tank.
AAAAAOIH:ASEOHSEOFH:SEIHF:EKF: RUUUUUUUUUN
Was my response, pretty much.
2)End of Swamp fever, at the mansion, a tank comes, no biggie, we throw some boomer bile at it, and I mount the machine gun. Soon, it's dead. Then, another tank climbs up the side of the building, so we all jump down and run, except for Rochelle, who gets incapped. Our last option was to wait at the gate, as another tank comes and incapps Coach, and then me, as we kill it. Not to worry, my kind cousin will get me u-OHGODTAAAAAAAANK! Coach is dead, I'm black and white, my cousin is on red health, what do I do? Run straight into the tank.
"RUN CHESTER, RUN"
He did get to the boat, but it was close.
