Physics noob, can someone explain this?

[Orbyt]

Read this on a recent AskScience thread on reddit:

"Theoretically, if you kept pressing your finger against the table enough times, at some point the assembly of atoms in the table and your finger will be aligned so that your finger would go through the table. It'd then be stuck, but that's what Walter Bishop is for."

Can someone explain this? Heres the original thread for some context: http://www.reddit.com/r/askscience/comments/2wflpy/its_my_understanding_that_when_we_try_to_touch/

There's an old thread on PF about this that may answer your questions.
