A Few Questions...

Remember this from the olden days? Mr. Microphone? A few questions:
1. Isn't the car a bit too crowded as it is, for them to "pick you up later"?
2. Why the repeating of "Jingle Bells"? The company couldn't find any other songs in the public domain?
3. Weird how the blonde at the end is in the house, and, on the cover of the box! Talk about meta-fiction!
4. The "professional uses Mr. Microphone for rehearsing," but she's playing in front of an audience.
5. And, finally, at the beginning, when the guy says the party is getting a bit too quiet, and he pulls an elongated pink object out of his coat pocket, well, visions of -- I can't say it.
