Tiger Woods gets trolled by AARP after awful start at British Open

It's been a rough 12 hours for Tiger Woods.

The 14-time major winner started Thursday by bogeying the first two holes of the British Open en route to his worst round as a pro at St. Andrews.

To add insult to injury, AARP took aim at the former world No. 1.

Ouch. Talk about kicking someone when he's down. But this isn't some random shot. When asked Tuesday about potential retirement, Tiger defiantly said that he doesn't have his "AARP card yet."

But after shooting 76 on Thursday, Tiger might have bigger worries than getting zinged on Twitter.
