This is animated gif of a bearded man saying "I'll tell you... I don't know" before walking away. I've seen this used as a reaction gif whenever somebody is unsure about the answer to a question that they should know.
Update: This is the character Tevye from the movie Fiddler on the Roof (1971). The character was played by actor Chaim Topol.
An animated gif that shows different website's reactions to bad things / news. The Reddit guy is unhappy, but not overly shocked. The "Real World" girl is horrified. The "Internet" is horrified to a lesser degree. Then you have the 4chan guy, who is unable to control his smile.
This is based on the popular Survivor Gif.
An animated gif of Charlie Adam's goal against Chelsea on the 4th of April, 2015. This wasn't even a half-line goal; he belted it from a few yards inside his own half!
This was during the game at Stamford Bridge, which Chelsea went on to win 2-1.
