Sheldon Cooper For The Win

fujiidom:

Sheldon: You’re asking me to keep a secret?
Penny: Yeah.
Sheldon: Well, I’m sorry, but you would have had to express that desire before revealing the secret, so that I could choose whether or not I wanted to accept the covenant of secret-keeping. You can’t impose a secret on an ex post facto basis.
Penny: What?
Sheldon: Secret-keeping is a complicated endeavor. One has to be concerned not only about what one says, but about facial expressions, autonomic reflexes. When I try to deceive, I myself have more nervous tics then a Lyme disease research facility. It’s a joke. It relies on the homonymic relationship between “tick,” the bloodsucking arachnid, and “tic,” the involuntary muscular contraction. I made it up myself.
