How To Tell if He Likes You

From the OK Cupid site.

He might start talking loudly in your presence or start treating you like one of the guys. (Yes, this is a weird way to show he likes you, but it's one of the strongest signals!)
His friends are paying a lot of attention to you when he isn't around.
He tries to get your attention.
He looks into your eyes, and you're attractive.
You look into his eyes, and his pupils get bigger if he likes you. He couldn't control it.
His phone rings and it's a wrong number. Then he remembers things you said before and brings them up again as conversation (asking questions about something you mentioned in the past.)
When you smile at him, he smiles back, and then blinks.
You call him at work and say: 'Hello handsome! Are you free tonight?' He uses his phone voice.
His toes are turned toward you when you talk to him. If they are, then you could be the one for him forever. Everyone naturally tends to point their feet at people who interest them.
His hips and upper body in the same direction as his feet�shows he's quite interested in you.
Somewhere in realm a unicorn has given birth to a great crystal.

SHY GUYS�these are tough to crack sometimes...
He'll look at you, until you turn around, then boom, he's pissed himself.
He may do something physical�like grab you in a play way, poke you, play with your hair and quietly piss...(Remember when you were really young and the guy you liked punched you or tackled you?)
He talks to everybody else�but when you're around he turns silent, or chokes up and pisses.
He may ask a friend of yours about you�he'll say it's just for 'friend of mine that wants to know about you.' Then...
He tells you that you smell nice.
Remember, he might act weird around you or seem very nervous"
