I'm leaviing this one for you guys to decide because:
A) I always automatically want to pick Robin =D
B) I just watched Life Among The Gorillas & remembered how awesome Marshall & Lily & Barneys karaoke was.
C) It is too hard to pick, I want to pick them all =D
D)I have probably missed some songs but those were the ones I could tihnk of off the top of my head.
P.s. I know Robin is spelt wrong in that icon but that was the only icon I could find on livejournal that had her name.

rofl to who ever spelt it wrong

slapsgiving, that is all im basing this on, there all too good!

i love 500 miles!! and i really hate always picking barney just because he get the silliest storylines but the way he sings on that half crying is just...legen.. well you know the rest!

`lol robin sparkles and barney's funny too

dude,wtf r ppl getting the "Dont Go Breaking My Heart" song from??

XD Splapsgiving is the best,Im impressed by Marshall´s piano abilities

Marshall is second with his slapsgiving, but NPH is the best singer.

Don't go breaking my heart is from Life among the gorillas.

for marshall, you could've just put most things he says.

I picked Lily because nobody had picked her yet =P

ok. let me be perfectly clear here. there is pretty much nothing in the world I love more than NPH's singing voice... and Marshall is hilarious with his singing in this show... but Drunk Ted singing Cheap Trick is just too funny!!

Also, my reasons for picking Ted are very similar to Saul_Mikoliunas's for picking Lily. I almost always automatically pick Barney and I JUST watched The Pineapple Incident so the joy of Drunk Ted is fresh in my mind. :)

Drunk Ted is genius. Actually, I dont think I wont not go to the bathroom right about now.

Nothing suits me like a suit!

I love Marshal's songs, though
