Words that start with silent letters?

A few years ago I was with a group of people and we 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 “K like knife,” “G like gnat” “P like pterodactyl” etc. I wasn’t able to think of too many examples but figured this was a perfect question to turn over to the collective. Besides those two examples, what other letters appear silently at the start of a word?
