As Kim Kardashian knows very well, one should always keep their receipts. They might come in handy for calling out someone lying about your husband or to thwart a paparazzi pretzel scheme.

Kardashian found herself on one end of this odd situation this week, when paparazzi photos of her brother, Rob Kardashian, began rolling out in prominent celebrity and tabloid magazines. The photos themselves are inconspicuous and pretty normal for a celebrity snap: Rob apparently went to a Wetzel's Pretzels to consume some doughy goodness, and was simply seen walking along a California street en route to the store. So, what's the big deal? Here's where things gets weird.

As Buzzfeed points out, this is the "first time" Rob has been seen in public in weeks, following the aftermath of his custody battle with ex-fiancée Blac Chyna. An economic translation: Whichever paparazzo snaps him first, ideally looking sad and depressed, was bound to get a decent payday. However, the photos in question weren't actually new, and Kim uncovered the paparazzo's attempt at a quick cash grab.

"Wait I just saw pics of Rob online & called him to tell him I'm annoyed he didn't bring me back any Wetzels Pretzels from the mall...." Kim tweeted on Wednesday night. "Butttt the pics are from Father's Day at Disneyland & the pap agency are reselling them as if they're new & made up the location, how shady! ... Yeah SUPER SHADY."

Going one step further, Kim even shared a photo of Rob and his daughter, Dream, at Disneyland the same day in June that the paparazzi photo was initially taken: "This is the same day back in June," she tweeted. As further evidence, Rob also previously posted about the family day-trip on Instagram, thanking the resort for the "best" first Father's Day he could've asked for.

Say what you want about the Kardashian family, but you sure don't want to mess with them and their pretzels.
