Is this the last of Lionel in this series?
If so, then good riddance. Ding, dong, the witch is dead.

Marshall and Lionel
I think its pretty clear that they're eventually going to be each others' boyfriends, which is sad, because I like Marshall far too much to see him spend any length of time with that douchebag.

no mention of the best line in the episode?
"when she was in 5th grade, all she wanted was to be exactly like Anne Frank."
