As if you needed another incentive to drink a McDonald's Shamrock Shake every day for the next month, here you go.
In honor of the shake's 50th anniversary, McDonald's is holding a contest where someone will win an 18-karat GOLD Shamrock Shake cup with 50 emeralds and white diamonds on it. The cup is worth $90,000.
You'll be entered to win it every time you buy one of the shakes through the McDonald's app.
If you just HAVE to have the cup, they're also auctioning one off on e Bay for charity. The price is up to $30,000 right now, with a little over a week to go.
