Texto Original - Inglês - How come I can't poke you?

The question is:
"How can't I poke you?"

Thanks jedi2000
J'ai cependant déjà entendu ce "how come", à mon avis cela devrait dire quelque chose comme "comment se fait-il"...mais je n'en suis pas sûr, aussi je crois plus sage de demander à Lilian.

Lilian, I've already heard this "How come", is it correct English? Does it mean something like "Oh! Come on!" ? Or doesn't it rather mean : "How is it possible that..."?

No, actually "how come" means "why"

Thanks Lilian! I edited this text though, as there were too many mistakes ("i" instead of "I", "cant" instead of "can't", "u" instead of "you" and so on...
