Adventure Comics #130

Using his X-Ray vision, Clark spots flaws in the construction of the rides at a newly-opened amusement park. Changing to Superboy he anchors the faulty ferris wheel until the passengers are safely on the ground. Salesman Herbert Binns complains to his boss Hugo Crowl and threatens to alert the police if any further faulty rides are sold. Crowl reminds him of a clause in his contract, whereby he can be fired if he doesn't make a sale as ordered. \"Sell a refrigerator to an Eskimo.\" Superboy helps him do just that, as well as with further seemingly impossible orders.
