BillyBrowser is a Billy Mays themed web browser for Android, made mostly as a joke quite a while ago. But it actually works pretty well. It should work on all devices running Android 4.0 and newer. I have tested it on every device I own and it's worked on all of them. Note: You have to enter http:// or https:// before a URL, otherwise it does not work. Below are a few screenshots of it running on my Nexus 6. Click the images for a full-size version.
