Once our party got hired as bodyguards for some noble. For the night everyone got a separate room in his castle. Just before he fell asleep, our barbarian heard several footsteps echoing throughout the corridor, stopping right before his room. He listened for awhile and after some time the unidentified people (in reality the captain of the guard making his nightly rounds) have gone away.
He spent the rest of the night sitting on the floor with his two handed sword in his lap, rocking back and forth whispering "They'll come soon, they'll come soon."
Recently I made an orc warlock, with an endurance of 21 (20 being the racial max + gifted background, similar to Fallout's). That basically means immunity to anything that is less deadly than an extra strong poison. Our GM's reaction? "You're thirsty. Oh look, puddle-beer!" My char found it tasty.
