hehe.. Boy George?
Ok seriously here's the low-down on B
per lovely wikipedia.org
In English and most other languages that use the Latin alphabet, b denotes the voiced bilabial plosive /b/, as in bib. In English it is sometimes silent; most instances are derived from old monosyllablic words with the b final and immediately preceded by an m, such as lamb and bomb; a few are examples of etymological spelling to make the word more like its Latin original, such as debt or doubt. In Estonian, Icelandic, and in Chinese, b does not denote a voiced consonant; instead, it represents a voiceless /p/ that contrasts with either a geminated /pp/ (in Estonian) or an aspirated /pʰ/ (in Chinese, Danish and Icelandic), represented by p. In Fijian b represents a prenasalized /mb/, whereas in Zulu and Xhosa it represents an implosive /ɓ/, in contrast to the digraph bh which represents /b/.
