Mom's sons

Walt, Larry and Ignar (listed oldest to youngest) are the sons of Mom, owner and CEO of Mom's Friendly Robot Company. It is possible, that the Professor is the father of Mom's three sons. This is supported by the passing physical resemblance of Ignar and Walt to the Professor, but while Mom's relationship with the professor fell apart over seventy years ago, and these guys seem to be in their late thirties. She did say that the professor was the "only man I ever loved". They each work as assistants to their mother and each own 0.1% of the company. Walt has stated that he'd like to marry someone like his mother and Larry has been seen on a date with Hattie (thanks to Bender's dating service).
