I've heard Stuck in the Middle in one store, and I halted suddenly and told my friend, "AHHHHHH GAHHHHH asd;oqkweroej IT'S MIKA!!!!!" She gave me this look:
Then I yelled out, "I love Express!!! (the store I was in)" When I was done browsing for clothes, I had to stay in the store until the song was over.
