I was about to say something to prevent this room from freezing - of course, it can be unfrozen by mods, users are supposed to post such request in this room.
And Google Books - although among the opt results, some are with this joke and some are unrelated.
Good that there was an explanation. I thought that is is supposed to be about hibernation.
I did not know this pun. (I guess people who aren't native English speakers have harder time guessing the intended meaning from the picture - but I guess even for English speaker it could take some time.)
