For example, Man on the Moon came out in 1999, and a strip explains that a teenage Bobby has just seen it. Big Momma's House came out in 2000, and now it is suggested that Bobby first saw it as a child!



And that's to say nothing of Alan not initially being obsessed with Big Momma. The 2006 January 30 strip shows him switching his devotion from Inspector Gadget to Big Momma.
