"I'm warm and soothing. I'm like a human bowl of tomato soup."
Why it's apropos: Sheldon might be the only person who has ever used the words "warm and soothing" to describe, well, Sheldon. While his humor can be dry as a salty cracker and his honesty blunt like the rounded edge of a spoon, our beloved Shelly certainly has his heartfelt moments.
Remember when he sweetly sang "Soft Kitty" to Penny when she was sick? Or the time when he comforted Howard after his mother passed? Though the instances are few in number, the times Sheldon has shown compassion to his friends are as special as any bowl of lycopene-filled soup.
