We all know it had to be a wamer who pulled this heist as what other plausible reason would somebody need that much whipped cream other than some messy fun.

We used it to fill our Pie Slide!

Quote from Yahoo news;
Guelph police spokesperson Scott Tracey spoke to the publication about the theft. He mentioned that officers are unable to speculate whether the theft was of the trailer or the whipped cream. "We won't know for sure what the motive was."

No I think we all know what the motive is.

I have an alibi. Lol
