Philly Has A September Problem | Go Birds T-Shirt
Every September, Philadelphia develops the same problem.
The Eagles come back, the city loses its mind, and rational thought goes out the window.
This vintage-inspired Philly football tee features our official Bird Brain Meter, charting the annual journey from Normal to Optimistic, Delusional, Super Bowl Parade, and finally full-blown Bird Brain.
If you understand “Go Birds” isn’t a greeting—it’s a lifestyle—this shirt is for you.

Philadelphia Has A September Problem.
Every year.
The Phillies are still playing.
School is back.
The weather starts cooling down.
And then the Eagles return.
That’s when the city completely forgets how to act.

Featuring our distressed vintage Bird Brain Meter, this design tracks the emotional state of every Eagles fan:
- Normal
- Optimistic
- Delusional
- Super Bowl Parade
- Bird Brain

Whether you’re headed to the Linc, the sports bar, the tailgate, Chickie’s & Pete’s, Xfinity Live, your buddy’s garage, or screaming at the TV from your couch, this shirt tells everyone exactly where your head is at.
And let’s be honest…
By Week 1 we’re all Bird Brain.
