Hahaha. I saw this earlier on Twitter. I love the end.
Haha, excellent mash-up! I happen to be a subscriber of this editor, this guy did an Expendables/Toy Story mash-up a while back. wink 
I love Carlās face at 0:15 
He just looks like āOh, not again!ā I guess this isnāt the first time Russell randomly burst into song.
That made my day. Normally Iām not a Lady Gaga fan, but this was perfect. 
Oh, my gosh.
And thanks a lotā¦ OK, so Iām really out of touch with popular music. I know thereās this singer called Lady Gaga, but thatās about it. Then I saw this - and the music was so catchy, not only did it get stuck in my head, I had to go find something on youtube so I could hear the rest of the song (found a clip of her performing it on "Ellenā). Thanks for helping to drag me into the 21st century.
I showed a few of my friends and my sister this video. They think itās one of the coolest things ever! (well on youtube at least!) 
I love it!! Itās soo amazingā¦but stillā¦my favorite Up Youtube mashup is the Upular Remix by Pogo.
hahaā¦ thatās hilarious! 
Whereās that at?
I am a really big Gaga fan and this was great.
lol wow. That was definitely amusing
That was cool and irritating at the same time. How did they do that?!?!?!?
lol, It is stuck in my head now.
Best ever
How people come up with these amazing things, I will never know.
that.was.AWESOME!
I thought it would be Upular, but this was unexpected and hilarious.
Ugh, I HATE that song! 
The Video is good but i donāt like the song to 
I laughed at this response more than the video, as too much of the time when a new face appears on those supermarket checkout line magazine racks, I have no clue as to how they became so famousā¦ I even ask Wall-E if he knows and he just shakes his head back and forth: āuh-uhā.
CarlĀ“s facepalm was priceless.
This video is full of win. And the best thing is that RussellĀ“s voice actually fits the song. Oh man.
This is awesome. And I canāt stand Gaga, either.
