Mrs. Damm and her children are seated on the porch when the postman arrives with a letter stating that their wealthy uncle would visit them. Mrs. Damm hustles the children into the house and they all get busy tidying things up for the expected guest. The boy feels the importance of the event but his sister is so lackadaisical she can't enter into the spirit of the occasion. Mrs. Damm, in addition to numerous other provisions, goes to the cigar store and orders a box of "perfectos" sent home. The tobacconist wraps up the box of "smokes" and lays them beside a box of trick explosive birthday cigars ordered by a previous customer, placing the name and address of each customer on the respective boxes. After Mrs. Damm leaves the store a meddlesome chap comes into the cigar store, looks at the cards while the proprietor is busy and gets the addresses on the boxes mixed; the consequence is the birthday explosives are sent to Mrs. Damm and her cigars are sent elsewhere.
