Jugglers often come up with very poor, but quite amusing excuses when they drop props. Here is a selection:

• Whoops! Sudden gust of gravity there.
• A drop is good! It's a learning experience.
• (Shakes prop) Batteries must be low.
• You'd drop if you were trying it!
• I touched it.
• (Drop the rest of the props) I meant to do that!
• At least it didn't hit someone this time.
