SEASON 3 spoilers
Dexter and Prado are buddies and they get a Pizza delivered, and it arrives uncut. WTF is that? The only pizzeria that delivers unsliced pies in America? Or was that a very lame attempt to try do the whole Dexter slice-of-life thing. Cause thats weaksauce.

Better writing would have had Dexter re-slice the pie because the pizza man did a shotty job back at the pizzeria; however, that would kinda drift into Monk's territory.
