When thinking of who to use, to entertain at the next anniversary party, consider a comedian. Make sure that the one you do choose has material that is appropriate for the partygoers. You would hate to have someone telling adult jokes at a party with a lot of little kids there.
Comedians are people who put smiles on our faces naturally. They do it by twisting reality into something that is funny. Think of all the times you needed a laugh and thought of your favorite joke. Now picture this occurring for an hour. This is what will happen if you go to see a comedian.
