Yeah, a urinal. There was this Tiny Chao Garden sprite of Sonic that for me looked so much like he was taking a leak that I made the urinal to go with it. Hence it's scaled a bit bigger than normal Advance sprites. I had it as my sig here years ago, and someone commented he'd been peeing for an awfully long time, and edits ensued.
My favorite by far is the last one, done by Sep. It's such a bad joke that it's great.
I might do a smaller version at some point for kicks.
And yeah, the Picklehog, as I call him, he looks like he's high or something.
Thanks, you're very kind.
(on a related note, I also made the Advance sprite-derived emoticons used on this forum, years ago. :3 )
