I can't remember much of this series, let alone a title. But as a child I recall it being funny and a great read, at least for the first book or two. The main character was a young wizard I think, and his companion had an evil club that could not be owned, but only rented. Occasionally, a demon would appear and demand payment, and if payment wasn't made they would be set upon by demons. Also someone almost drowned in pudding at some point I think, but this is all fleeting memories. Please help, I really want to re-discover this series and see if my sons will enjoy them. Thank you for any help!!
