Lyrics:

When I feel happy, I can smile The biggest smile I know. Then you can see my happies show. Ha, ha, ha, hee, hee, hee. Come on get silly and laugh with me. Giggle gaggle, wiggle waggle, ho, ho, ho. When you're feeling happy, let it show. I got the sillies and when you get 'em, You'll be silly like me. I can't stop laughing as you can see. Ha, ha, ha, hee, hee, hee. Come on get silly and laugh with me. Giggle gaggle, wiggle waggle, ho, ho, ho. When you get the sillies, let it show. I've got a tickle, it makes me wiggle. It makes me jiggle too. Can't hold it in. I just gotta giggle. Ha ha ha, hee, hee, hee. Come on get silly and laugh with me. Giggle gaggle, wiggle waggle, ho, ho, ho. I've got a tickle, here I go! Ha ha ha, hee hee hee. Come on get silly and laugh with me. Giggle gaggle, wiggle waggle, ho ho ho. When you're feeling happy, (Feeling happy) When you've got the sillies, (Got the sillies) When you've got a tickle, (Got a tickle) Let... it... show!
