I liked the first one. I liked the fifth one. I quite enjoyed the other two you posted, although i think i may have invented my own punchline for 'VIKING BOOBS'.
However.
The second, third and fourth comics you posted are shockingly poor by your high standards (and i'd like to stress the 'high' in 'high standards') and you've committed the cardinal sin of EXPLAINING THE JOKE IN THE TITLE OF THE COMIC
*slap* for doing that, but well done on the comics as a whole. Mostly. *thumb up*
