I'm not sure this couple QUITE thought through the logic behind their plan.

There's a 25-year-old woman named Heather Murphy from Wareham, Massachusetts, and she had a court appearance on Wednesday for driving with a suspended license last month.

Her 33-year-old boyfriend Jason Willoughby was going with her to court, and they wanted to make sure they looked good.

So last Tuesday, they went to Walmart . . . and SHOPLIFTED some nice court clothes.

But they got caught by a security guard, and the cops came and busted them as they were trying to leave the store.

They were both arrested for shoplifting.
