My bonnie lies over the ocean
My bonnie lies over the sea
My bonnie lies over the ocean
Oh bring back my bonnie to me

Bring back, bring back,
Oh bring back my bonnie to me to me
Bring back, bring back,
Oh bring back my bonnie to me

With this version you can get everyone to stand up or sit down or put their hands up in the air or down,whatever you want really, every time a word starting with B is sung. So on the first bonnie you stand up,and on the second you sit down etc. You can then make it as complicated as you want by splitting the audience in 2 aand having them do the opposite actions to eachother.

Other versions include

My bonnie has tuberculosis
My bonnie has only one lung
She coughs up a bloody solution
And rolls it around on her tongue

Rolls it, rolls it,
rolls it around on her tongue her tongue
Rolls it, rolls it,
rolls it around on her tongue her tongue
