At lunchtime on Wednesdays, it's hard not to smile at Purdue University.

Cameron Brown and Brett Westcott will seeto it.

Brown and Westcott are known on campus as The Compliment Guys. They stand at a central walkway each Wednesday from 12:30 p.m. to 1:30 p.m. and unabashedly shout compliments to everyone they see.

The Chicago Tribune profiled the duo recently. A snippet:

"The duo fire off the compliments so quickly that an attempt to count a minute's worth was unsuccessful. There were at least 40. They liked headphones. Bikes. Gloves, earmuffs and scarves. A floral backpack. And even a lanyard.

If a tour group walks by, they try to comment on everyone in the crowd. On Wednesday, they told a professor to enjoy his coffee, thanked the groundskeepers for their hard work and prodded someone eating an apple to "stay nutritious."

 Here's the story.
