Poor old Sim is worn out by the heat of the day and tries to get a nap in the big chair, but a gay wasp in full dress charges at his bald spot. Sim jumps up and fights the enemy with chairs, vases and anything that is handy for attack. The wasp is too fly to be hit and gives Sim the laugh at every onset. To soothe his nerves he tries to play the piano with hands, feet and face, but fails to derive any melodious comfort. Driven to frenzy, he calls his man and, in his rage, swallows him up; he becomes delirious and is attacked by a diminutive marble Apollo who bests him at every turn. Crazed beyond measure. Sim hurls himself through the third story window of the house opposite, there to escape his tormentors. He wakes up and is seen posting Lubin bills.
