What problems does one run into when 'dropping' names in writing? For example, in the second chapter of the story I've just written, the protagonist is watching a sitcom and notices that one of the actors has changed quite a lot since the sitcom was made (e.g., Blackadder the Third and Hugh Laurie). Another example: my protagonist finds that a Honda motorcycle suddenly materialises in the middle of a room. Should I find a publisher that is all giddy with excitement and wants to discuss printing my book, would I be asked to not mention names? Or would they simply gloss over the fact that I've blatantly compared one of my characters to, say, Mr Bean?
