Fictional characters - need to cheer myself up

Had an utterly c**p day, mainly due to work so looking to come up with a fun conversation to take my mind off things

So, if you could be best friends with one fictional character who would it be? And if you could date one fictional character who would it be?
They can be people off TV shows, films, books, comics anything

Mine (at the moment) would be 

Best friend - Hawkeye Pierce from MASH
Dating - Chrissy Plumber (Paula Wilcox) from Man About The House
