Mom is a very old but
very ruthless founder and owner of Mom s friendly robot company, one of
the cornerstones of it being Mom's old fashioned robot oil which is used
by most robots on earth. She has three sons: Walt, Larry and Ignar. They
all work for the company, helping to do her dirty work. Back during the
time when Farnsworth worked for Mom's Friendly Robot Company, they had
a fling which ended when Mom kept turning Farnsworth's cute inventions
into mad, killing machines.
