How cheaply could you temporarily trick folks into thinking you hit a big jackpot?

So you didn’t win the big jackpot (let’s say aftertax lump sum is $150million), and assume you have about 6 weeks before the true winner comes forward. (Excluding the creation of a counterfeit ticket) what is the cheapest/clever way to make people around you think you’re the winner, even though you’re constantly denying that fact? Ok I’ll go first: take over a short term lease (<12 months) of a Porsche, and take a quick trip to Paris by myself. Any better ways?
