As the most conceited member of the I.O.U. College Fraternity, Wallie is the source of much amusement among the boys. They see him read the posters announcing the appearance of Mlle. Felice, a musical comedy star, and watch him buy flowers for her. They tell Bob, an old friend of Mlle. Felice, who has sent him a pass for a box at the show. “To put one over on Wallie,” they all decide to go and leave him out. At the matinee they see Wallie in another box, his eyes glued on Mlle. Felice, and looking like a sick calf. After the show Bob and the boys call on her and ask her to make up as an old woman, explaining the little joke they have planned. At their suggestion she writes a note, thanking Wallie for his flowers and making an appointment to meet him that evening. Wallie is overjoyed, and while the others grin, he says, “They all fall for little Wallie.” That evening Wallie, “all dolled up,” and carrying a bouquet, starts for the theater, followed cautiously by those in the secret. While he is waiting, with a “Be still, my heart.” expression, Mlle. appears in her old lady make-up. She takes the flowers from the stupefied Wallie, and smooths his hair with loving grimaces. He finally succeeds in excusing himself, only to find the boys barring his way. Mlle., unobserved, takes off the make-up and confronts Wallie. As a dazed expression of admiration comes over his face the boys shove him into the waiting auto, order the chauffeur to put on full speed, and poor Wallie is soon out of sight. Mlle. gets into her machine and the boys, still laughing, give a wild cheer for her. Their little joke on the self-important Wallie is a success.
