This Week in Viral Videos
This week saw a variety of viral videos, from a nostalgic flip book to celebrity cameo appearances ... even ninja references. (hi-yah!)
Leading the bunch is the 'Late Night' video of Jimmy Fallon singing Miley Cyrus' 'Party in the USA,' using a distinct, perfected impersonation. We realize nothing could beat the all-too-catchy original, but this version is pretty good competition.
See what other viral videos we picked as our favorites this week.
