Abstract: A shop horse pad of closed cell foam is cylindrical in shape and having a central radial opening provided therein. An axial slit is provided along the length of the pad that creates two axial edges. A strip of adhesive is arranged along at least one of the axial edges. A covering strip, of preferably cellophane, is provided on the strip of adhesive such that when it is removed, the two axial edges adhere together. In this manner, a user may simply force the pad over the horizontal work tubing of the shop horse and removes the covering strip. Thereafter, the axial edges of the pad are forced together to form a solid pad about the exterior of the horizontal tubing.

Abstract: A digital toy which produces a random response to an audible inquiry. During the time of the audible inquiry, a switch is depressed. During that switch depression time a random response of the yes or no type is determined and at the same time an enabling signal is generated so long as an audible inquiry has been detected. Upon release of the switch the enabling signal causes binary coded decimal lights to flash and simultaneously tones to be sounded for a time period followed by a buzzer sound after which the predetermined response is displayed.
