Under 21

The other night I tried to go to a show
 But the man at the door he told me no
 He said "No one under 21 allowed"
 But he must've been stupid 'cause I saw my friends in the crowd
 He said "You can't buy an alcoholic drink"
 So we don't care what you really think
 (Chorus)
 Why this happened to me
 And the show was for free
 It sucks to be
 Under 21
 So I went and got myself a plan that would work
 And I went home and got a real short skirt
 And I flirt my way right through that god damn door
 But once inside the music was no more
 Well I guess I got there just a bit too late
 I guess it's just my luck
 It's just my fate
 (Chorus)
 I only want to have a little fun
 But every time I try they tell me "You're not 21"
