Origin of this phrase

[pontifex]

I apologize in advance if this is derogatory in any way, but i heard the phrase "in like a porch climber" recently. It seems to mean the same thing as "in like flynn" btu I have no idea where he got it from. Googling the phrase shows me where several people use it and confirms my thought that it is similar to "in like Flynn", but no actual origin.
