"Soooo, who's the girl?"

Ev had a little "funny" happen at homecoming over the weekend...
He was at the dance and a couple of his friends came over and started chatting with him and Emma.
Ev slugs his friend Ryan in the arm playfully and says, "Soooo, who's the girl you came walking in with?  Huh?  Huh?"...grinning from ear to ear and thinking maybe Ryan brought a date after all.
All the guys start cracking up.
"What?" Evan says.
"SHE'S MY SISTER!", Ryan says. 
LOL!
Too funny.
"Oops, sorry!", Evan says.
Teehee!
