Fortunately, The Milk by Neil Gaiman

Mom is off on a business trip, leaving father in charge.  Unfortunately, they have also run out of milk for the cereal and dads tea.  Father states he will go down to the corner market and get the milk, but the children are left waiting and waiting.  When father returns, he tells them the tale of how he encountered aliens, pirates, dinosaurs, time travel, volcanoes and a hot air balloon, all while saving the milk.   The illustrations are adorably done and really make the story.  Especially the ones of the children's expression as father tells his tale, beautifully detailed.  I think this would make for a fun read aloud, children could even be encouraged to add their own adventures to the tale, which I think the story lends itself for very well.  It's silly and improbable and funny, defiantly would make for a great gift too.  There is also another version in the UK with illustrations by Chris Riddell that would have been fun to see.  Review copy was from the public library.
