River Park Puns

My morning walk with the dog was cut short today. There's a park we usually wander through so she can sniff and explore, but today we couldn't get in because the path was blocked by an army of angry geese.

I was telling my mom about this and she mentioned there are geese at the river where she and a friend take their dogs, too. She said they must all be in town for some kind of conference. Then she paused for half a second and continued:

I bet it's a religious thing. They're here to preach the goosepel.

(To satisfy the rule: that's a play on gospel.)
