Happy Birthday, Britta! You've always been faster in water than most of us are on dry land. We still haven't figured out if you secretly have fins hidden somewhere—you captured gold medals in the 50 and 100 meters freestyle at the Beijing Olympics so quickly that we barely had time to blink!Even speedier was your record-breaking splash into history books (we're pretty sure dolphins requested swimming lessons afterwards). Today, may your celebrations be as legendary as your Olympic wins—fast-paced, triumphant, and full of joy. Keep making waves wherever you go; you've shown repeatedly you're unbeatable both inside AND outside the pool!
