Once a world-renouned neurosurgeon, he slowly lost touch with reality after his meeting with
Simons Mith (q.v.) His subsequent animation of the formerly-BT AI led to his near-complete
loss of sanity. The hospital in Aberdeen from which he practiced released him and, in an attempt to protect their reputation, claimed his insanity was caused by syphilis.
Yer Mom's ability to exert his will upon small animals was heavily exploited under the puppetry of Simons. Horrible evidence of Simons' control over Yer Mom (and hence the control of the badgers) can be found
here. Yer Mom finally broke free of Simons Mith's reach recently. Thought to be in hiding, he has been purported to briefly reside everywhere from Njarðvík to Macquarie Island However, wherever he tries to go, he is under the constant fear that Simons Mith will meet him there. He better have an army of wallabys ready.
