As I do every week here on CoreBoobs, today I’ve gathered up a collection of Tumblr’s greatest hits, aka the funniest things ever shared on Tumblr . Sometimes they’re just one-off jokes, sometimes they’re threads of genius, and other times they’re perfectly placed zingers. Regardless of the timing or context, you can be assured that they’re the funniest things ever shared on Tumblr . And today I’d like to send a big shout out to reader Landon S. for sending me some pics to use! If you’re not following CoreBoobs on Tumblr yet, click that link because you’re missing out. And for those of you that haven’t seen this before, this is something I used to post every Monday over on Guyism, and this post will now live here on CoreBoobs each Monday. And if you’re looking for more funny photos make sure to follow @CoreBoobsOfficial on Instagram ! Changing gears a little bit, I want to make sure that ALL OF YOU know about the all new CoreBoobs iOS app that was launched last week.
