It's your birthday, and you're not here And it makes me want to shed a grouchy tear 'Cause on your day of birth, worm I wish you were on Earth, worm Instead you're high above The atmosphere Oh what can you do when your pet Is as far away as he can get? He's not in New Jersey, he's not in Cancun He's on his way back from a trip to the moon And I wanna say Happy Birthday I wanna say it face to face I wanna say Happy Birthday to Slimey But he's out there in space Oh what's a grouch supposed to do When he's feelin' this lonely and blue? I'm feelin' too sad to be grouchy and mean With me and the moon, and my worm in between 'Cause I wanna say Happy Birthday I wanna say it face to face I wanna say Happy Birthday to Slimey But he's out there in space Oh yeah He's out there in space Oh dear
