I know

[mr_cellophane]

an old cyclist who swallowed a fly
I don't know why I swallowed a fly
Perhaps I'll die.

I have only ever swallowed a fly once (though I have had some go into my mouth which were promptly spat out!), but I was so disgusted by swallowing a fly, I threw up so the fly was no longer inside me. Yuk!

 

[Matthames]

I had swallowed a fly today. What probably made it even more disgusting is that it probably had some lunch on some ruminant's left overs

I had mouthfulls of insects when out this morning. Around the lanes there were swarms of them.

Just cut to the chase and eat the horse.
