That "Prime Cracker" sketch from the Red Nose Day festivities earlier this year may have been banished to the sketch comedy universe, but that doesn't mean it can't still contribute to the main Toobworld.
As Detective Jane Tennyson faced off against Dr. Fitz Fitzgerald in the interrogation room, she asked the forensic psychologist how many murder convictions resulted from his methods. He had 17, but she trumped him with 42.
"42" is one of "The Numbers" from the Valenzetti Equation, a sequence supposedly found only in 'Lost', but which is universal throughout Toobworld and its many dimension - in this case, even in Skitlandia.
It's just a shame Fitz couldn't claim 15 or 16 convictions, both of which are also 'Lost' numbers....
