"Wands are only as powerful as the wizards who use them. Some wizards just like to boast that theirs are bigger and better than other people's."
--Hermione Granger (from Harry Potter and the Deathly Hallows)
Funny thing. This was the second time in the book where phallic humor penetrated the story. Without giving too much away, in the story Harry has to use someone else's wand. It's, ahem, smaller than his and he refers to using it as like "having someone else's hand sewn to the end of his arm." One of the first spells he tries with it is engorgio and it doesn't work (Viagra joke anyone?). Hermione's comment to this failure is: "It's all a matter of confidence."
Really enjoying this, the seventh book.
