Words that start with silent letters?

A few years ago a group of people were talking about how, when you have to spell your name over the phone, it’s common to say words instead of just letters – i.e. “D like Daniel, A like apple, V like Victor…” etc. We thought it would be funny if it were possible to spell out your name but use letters that were silent in the pronunciation—i.e. “K like knife,” “G like gnat” “P like pterodactyl” etc. They weren’t able to think of too many examples but this seems like the perfect question to turn over to the collective. Besides those three examples, what other words start with a silent letter?
