🛃 French border agent:
Excuse me sir, what is in the truck? Do you have anything to declare?

🚚 Truck driver: Just a cloud of 92 #antiprotons in an innovative portable cryogenic Penning trap.

🛃 French border agent: 🫠 🫠 🫠 I'm sorry, I think I owe you some money or something. I don't have the right form to deal with antimatter.

@nuthatch CERN has two official working languages: English and French.
