 We'll make a collection:
 
 	db.users.insert({name: "Tom", bio: "A nice guy.", pets: ["monkey", "fish"], someWeirdLegacyKey: "I like Ike!"});
-	db.users.insert({name: "Dick", bio: "I swordfight."});
-	db.users.insert({name: "Harry", pets: "egret"});
+	db.users.insert({name: "Dick", bio: "I swordfight.", birthday: new Date("1974-03-14")});
+	db.users.insert({name: "Harry", pets: "egret", birthday: new Date("1984-03-14")});
 	db.users.insert({name: "Geneviève", bio: "Ça va?"});
+	db.users.insert({name: "Jim", someBinData: new BinData(2,"1234")});
 
 So, let's see what we've got here:
 
 	$ mongo test --eval "var collection = 'users'" variety.js
