I don't know about you, but I am a fan of all things chocolate milk. So basically, just chocolate milk. I am obsessed. So naturally, I constantly have to think of excuses to not share it with other people. Here are some movie quote excuses you can use to ward away the evils of would be chocolate milk stealers.
1. "This isn't the chocolate milk you're looking for."- Dairy Wars Episode IV: A New Milk
They will quickly realize that they didn't want your chocolate milk at all after you tell them this!
2. "This chocolate milk is poisonous to anyone who has not built up an immunity to iocane powder." - The Princess Milk
Anyone who has seen The Princess Bride will know you are not joking about this very serious matter.
3. "THIS IS CHOCOLATE MILK." - 300 (Milk Cartons)
After you kick them into a bottomless pit they won't ask again.
4. "Frankly, my dear, I don't share my milk." - Gone With The Milk
If you calmly explain it to them in this Rhett Butler-esque manner, I doubt they will trouble you with chocolate milk related matters again.
5. "You can't HANDLE the milk!" - A Few Good Milks
Once they realize just how hard it would be to manage so much deliciousness, I guarantee they will back off of the entire chocolate milk issue.
6. "MY.. PRECIOUS MILK." - Lord of the Milks
Honestly, they might be so freaked out after this one that you may not ever have to deal with them again.
7. "Riiight, the milk for me. The milk made especially for me. The chocolate milk. The milk you aren't having. That milk?" - The Emperor's New Milk
I think this will put your opinion of them asking for your chocolate milk into perspective.
8. "I feel the need... The need for milk. (Chugs milk)" - Top Milk
After you finish your milk with a satisfied sigh, they'll probably just walk away.
9. "I'm the king of the milk!" - Titamilk
When you issue this bold proclamation, they will reminisce to the end of the movie when everyone freezes and no one gets chocolate milk and decide they are better off without it.
10. "They may take our lives, but they'll never take OUR CHOCOLATE MILK." - Bravemilk
They probably don't want to go to war with you so it's safe to say they will leave you alone if you quote this classic.
