The amazing tributes towards the memory of Robin Williams have been coming from numerous celebrities all throughout the week.

Some of the most heart felt ones this week, however, have come from Late Night talk show hosts, who knew Robin as "One of the best guests a host could have."

I think all of these tributes towards him are pretty emotional to watch. I teared up a bit myself just seeing it.
