Parodying any government or secret service agency is also a great way to create funny voicemail messages. For instance, you could say, "Thank you for calling the Slovakian Consulate. All our diplomats are out changing lightbulbs, so at the sound of the tone, please leave your details and any international secret you may have for sale." Creating funny voicemail messages that sound like they are from the mafia, the FBI, the CIA, or even the IRS can be a cool way to greet your callers when you are not available.
Friends and colleagues speak to each using first names only. So do people of authority. They do not call each other and leave voicemail messages asking for Mister, Miss, or Mrs. Therefore, when you call a person you want to do business with and you leave a voicemail message, refer to them by their first name only. Don't say mister, miss, or misses. Don't say their last name. Begin your voicemail message by saying only "hi/hello" followed by the person's first name. Or, you can even forget the "hi/hello" and just say the person's first name. That is how you show confidence and authority and separate yourself from weak salespeople.

For instance, a novelty shop could probably create a rather informal message, using sound effects that represent the type of items they sell.
