I believe in space bees

My sister hates my joke about space bees. She says I need to cut it from my set. Every time I tell it, no one laughs. My sister is in the audience, shaking her head. She doesn't see the point. I believe in space bees. I can't quite put my finger on it yet. There's something very true about it. It feels right to me. I know that when I can get a laugh on space bees, most of the time, I will have become the comedian I want to be.
