SAN ANTONIO -- Life under the big top is always a big adventure for the Dallas Cowboys.
Case in point: 1980s pop culture icon Pee-wee Herman made a surprise appearance at practice Thursday night -- fittingly, in the Alamodome -- in what can be described as an only-with-the-Cowboys moment.
As coach Jason Garrett addressed the players before the end of the workout, Pee-wee -- in San Antonio for an appearance -- posed for a picture with owner and general manager Jerry Jones and executive vice presidents Stephen Jones and Jerry Jones Jr.
His presence and appearance -- he was in true Pee-wee style, with his gray suit, red bow tie and platform shoes -- drew curious looks from the players as they made their way to the locker room.
The comedian, whose real name is Paul Reubens, is known for his lead role in the movie "Pee-wee's Big Adventure" and the TV series "Pee-wee's Playhouse."
"[Kyle] Kosier pointed him out midway through the two-minute drill," Witten said. "I'm like, 'Kosier, are you watching practice or are you seeing Pee-wee Herman?' The problem is only like three guys in the huddle knew who he was. The older guys know Pee-wee Herman.
"I think [rookie] Tyron Smith looked at him like, 'Who's that?' He didn't know him. Gosh, I'm showing my age. I used to be one of the young guys."
Having celebrities and athletes from other sports at training camp is not a new phenomenon for the Cowboys. Former boxing world champion Erik Morales attended Thursday's walkthrough to promote his Sept. 17 super lightweight title fight against Lucas Matthysee.
When the Cowboys have held training camp in Oxnard, Calif., more star-studded attendees such as Magic Johnson, Kevin Costner and Dennis Miller have dropped by.
