After listening to this conversation, Bob was abandoned on the table at which Wonka and Derby had been sitting whilst they engaged in, amongst other activities, coat-swapping.
Not so, dear friends, so do not panic. For you see, once a personality is given to an object it is no longer simply an object. The Oompa-Loompas who came along to clear the table of scones, jam, cream and Bob found that, try as they may, they could not bring themselves to throw Bob into the hopper to be washed and 'killed' with all the other lemons. One of the cleaning staff took Bob home and confided in him that night that he was feeling lonely and needed a pay rise to pay his girlfriend's father the necessary dowry to get his permission for his girlfriend's hand in marriage. After talking to Bob, the Oompa-Loompa made up his mind to ask Mr Wonka for a pay rise the very next day - and got it.
Word got around that talking to Bob could solve all your problems. Of course, this could be because in talking to an inanimate object and 'making up' the replies yourself, you are essentially counselling yourself through your problems. Or it could be the magic of Bob. Who knows? Certainly not me and certainly not the Oompa-Loompas who, having taken Bob and hidden him in the Citronus temple deep in the Oompa-Loompa village within Mr Wonka's factory, consider him one of the wisest beings in the factory, excluding Mr Wonka of course. Bob is stationed inside a black velvet case, preserved carefully that no mould or dehydration can mar his appearance. And it is there that depressed or confused Oompa-Loompas (and on one rare occasion, a chicken) are taken to sort out their problems through a private conversation with Bob. Some say that simply being in his presence is enough - others maintain that constant, unblinking eye contact is essential for success.
So now you know. Go ahead - try it for yourself. Stare at the picture and tell Bob all your problems - I guarantee nothing except that you will not be judged or condemned on anything you say to Bob. Listen carefully to the responses that come to mind - and think carefully about each one. Better yet, go and liberate one of Bob's relatives from your local store and have a private conversation with him or her in your own home where no-one can hear you.
And, of course, if you can't see an end to your problems after conversing with your chosen lemon, you can always cheer yourself up with a slice in the drink of your choice.
