Welcome to PEEL Bend-aid,
It indeed is a quite sad episode, like some others of Futurama are. Jurassic Bark didn't bring me to tears, I have to admit that some other episode can actually do that... for whatever reason.
Here you have some threads where discussions about these episode have been started:Tearjerkers
andPoll: Tear Jerkiest Episode - This Time, It's A Poll.
As you see, people have already talked about that, which makes newer threads obsolete for now. So there is a high chance that your thread will be closed down once a mod comes around. Don't take it the wrong way, after all it's their job.
In case you need any help with PEEL I heartly recommend you to read our little FAQ, the PEELers' FAQ
. It's filled with a lot of tips and tricks to get around PEEL as well as a lot of guidelines of how to behave.
After all, enjoy your stay.
