Provably impossible (I know it has already been taken but you can have some maths to back it):

It *is* impossible.
Topology tells us that a figure can only be traced in one stroke without repeating a line if either:
a) Every intersection of lines (point) involves an even number of lines spanning from it
or
b) ALL BUT TWO involve an even number.

For further details, go to Wikipedia, or read the Maths "D1" A-level Textbook.

This figure has a (4) in the middle, and 4 (5)s, thus is not traceable in one stroke.

EDIT: Oh yeah, it was in Layton too. Funny; I was doing D1 at the same time as the first Layton came out in the UK, so I didn't need the in-game hint.
