Every Wednesday, from 12:30 to 2:30, Purdue University sophomores Cameron Brown and Brett Westcott, better known as the "Compliment Guys, " stand outside the chemistry building with their "Free Compliments" sign, rain, snow or shine to cheer up the student body.

Along a central walkway on Purdue University's campus, two students are on a crusade to make people happy.

To a passing guy dressed in Purdue sweats they say, "Love your school spirit."

To the woman carrying the trendy black bag: "Very nice purse." "It's very large."

And for the student who ran past them in knee-high leather boots: "I like your hustle." "I like your boots, too."
