M. Night Shyamalan-ed - when you set someone up for a big surprise, but it backfires

when you set someone up for a big surprise, but it backfires and they throw a tantrum.

I told my brother the surprise party was at his house. It was at his ex’s house.

I said the cake was chocolate. It was broccoli.

I told my dog it was going for a walk. It was going for a bath.
