| Once upon a time in a deserted little town | |
| An incubated boy was born and the tried to put him down | |
| Didn't have no muscles here | |
| Didn't have no fat | |
| But when he opened up his mouth ya heard the biggest trap | |
| They called him big mouth | |
| Big trap | |
| Loud mouth | |
| Mighty mouth | |
| Here comes the M-M-M-M-M-M-M-M-M-Mighty mouth | |
| No silver spoon, grew up too soon out on the dirt | |
| He took a big deep breath and popped the buttons off his shirt | |
| He's no zero oh he's a hero | |
| He's every mother's dream | |
| And all the boys could feel the noise | |
| They'd shake when they'd hear him scream | |
| They called him big mouth | |
| Big trap | |
| Loud mouth | |
| Mighty mouth |
