Blame it on the free beer. Or the number of porta potties — only 850 planned for a projected two-million-plus people.

Either way, Eagles fans pretty much went to the bathroom anywhere they could find along the parade route Thursday, (and climbed anything they could find, too).

Some fans found, um, creative ways to go.

Some really didn't want to lose their spots.

Others climbed on top of porta potties to get a good view of the parade.

Inevitably, this happened.

The bathroom lines were long hours before the parade — and that was before drinking got into full-swing (at least for some people).

"It's not going to work," said Sean Halstead, 26, waiting outside City Hall, where lines for porta potties were at least 15 people deep around 9 a.m. "Two million people, I say at least a million of them are drunk, which means they're impatient."

Jay Price, 29, sipping a morning Miller Lite as he waited in line, had a simple response for how people would start to relieve themselves: "Find a street."

Unable to find a porta potty, some parade-goers turned to police officers.

Some fans were urinating before even getting to the parade route.

Others gave up — or just didn't bother — waiting in line.

Still, not every porta potty was mobbed. Some near the Linc were wide open early on.

And for the record, this would happen in any city celebrating a sports title. So cut Eagles fans a break.
