Some really great choices here. Crazy People - always makes me belly laugh, especially the "hello" guy and his "hello song". Some Like it Hot - what a script, what a cast. That Touch of Mink - Cary Grant trying to get Doris Day into bed and all the mishaps that ensue - what's not to like? Calamity Jane - fantastic songs and gags. Crocodile Dundee - the sequel is just as good, too. What About Bob - Bill Murray at his funniest. Murder by Death - Maybe the title isn't so inviting, but the situations are brilliant! Victor/Victoria - one of the classics, surely. Flight of the Navigator - I've watched this so many times and it never gets old. Galaxy Quest Even a really bad day would seem brighter after one of those. EDIT: There are just so many, I keep adding!
