Wei-Hwa's Puzzle Challenge Number 24

Whyme Rhyme 2: Find the non-rhyming pairs of words that only differ in their first letter, such as LEMON DEMON.

Rules.
The words may or may not be proper nouns. Pronunciations are assumed to be standard American English, but these pairs will fail to rhyme in almost all dialects of English. (For more Whyme Rhymes, check out the archive.)

How to Play.
Simply type your guess in the box. Spaces and capitalization don't count, but spelling does! You can try as much as you want without penalty. If you have solved a puzzle already and want to see the original clue, try parking your mouse over the answer.
