A Saturday night outdoor movie experience at the Tennessee Titans' stadium turned into chaos when somebody forgot to disable the sprinklers.

The annual event drew a big crowd of families to watch "Minions" from the field and stands on Saturday, but everything didn't go exactly as planned.

It all started off fine ... just look how happy these people are.

Then the waterworks hit to literally rain on everyone's parade. Whoops!
