The Boston Globe (Marc Spears) reports: Just before the Celtics ran onto the floor to warm up for their 49th game of the season, rookie guard J.R. Giddens stopped his teammates to ask an important question. “I didn’t know how to go out when we were warming up,” said Giddens, after the Celtics’ 109-101 win over Minnesota yesterday at TD Banknorth Garden. “Some of the guys were making fun of me. I said, ‘Hey I’m usually taking a shower right now [after working out].’ So it was fun and I actually got to see the warmups. “Today it was like, ‘A uniform. Is that for me?’ They hadn’t taken it out since like preseason so they had stains on it . . . It was all right. I had a lot of fun out there.”
