Left the door wide open
 Didn't have a clue
 Thought that I had locked it
 The lock was broken too
 In you came like summer rain
 Filling up my heart and yours too

 I got all these symptoms I can't describe
 Tell me is there something that can be prescribed
 All these nights of losing sleep
 Left me in this state my heart goes

 Pitter pat
 I'm tongue tied
 I'm feeling all these butterflies
 My mouth is dry, it's hard to speak
 My heart keeps playing hide and seek
 I think [bad word] down with something, love-sick kind of flu
 I'm working up a fever and it's all because of you

 Do do do do do do
 All because of you

 I've been dead I can't kick
 No matter how hard I try
 My knees are getting weaker and I can't deny

 Falling faster
 Falling deep
 Felt it from the start
 My heart goes

 Pitter pat
 I'm tongue tied
 I'm feeling all these butterflies
 My mouth is dry, it's hard to speak
 My heart keeps playing hide and seek
 I think [bad word] down with something love-sick kind of flu
 I'm working up a fever and it's all because of you

 I'm in love
 It's all because of you
 (I can't keep from falling) x8

 Pitter pat
 I'm tongue tied
 I'm feeling all these butterflies
 My mouth is dry, it's hard to speak
 My heart keeps playing hide and seek
 I think [bad word] down with something love-sick kind of flu
 I'm working up a fever and it's all because of you

 Pitter pat
 I'm tongue tied
 I'm feeling all these butterflies
 My mouth is dry, I can hardly to speak
 My heart keeps playing hide and seek
 I think [bad word] down with something love-sick kind of flu
 I'm working up a fever and it's all because of you

 Do do do do do do
 All because of you
