I agree with motoki, you're doing it all wrong.
First, you need to make sure you have the "testingcheatsenabled true" command, an expensive car in your sims inventory and a sim with low motives.
Then you need to make sure it's 8-9 pm, not earlier or later, otherwise it won't work well. At this point you'll have to order one of your sims to go to the Bristo and have a drink inside, remember, INSIDE, then select the park icon (from the view town mode) and make your active sim to go there after he has some drinks, then just roam around the park and wait an hour or so, and you'll need to go to the other restaurant, the cheap one and have some more drink.
Just repeat the drinking action up to 3 am, then you stop and you'll be able to enter "razzledazzle". It may appear a message telling you that there's no such command, just ignore it, it's a decoy message to make yopu repeat it, if you repeat it you'll disable it, we don't want that.
This next step is important: you'll have to select the car of your sim and order it to go home, and then the fun part will happen: OMFGWDID!!!
