Based on the speech-is-getting-shorter theory I'd say 'please' will prevail because it's one syllable but in descending order of likelihood you'll hear:
- Take your feet off the sofa.
- Please take your feet off the sofa.
- Take your feet of the sofa, thanks.
- Kindly take your feet off the sofa.
- I'll thank you to take your feet off the sofa.
- Thanks in advance for taking your feet off the sofa.
- I would appreciate it if you would take your feet off the sofa.
- You sir: kindly be a proper gentleman, and take your feet off the sofa.
