I knew a smaller fellow who talked funny who could do just that--and saw him in action in a bar fight one night. Two very large fellows learned about the SAS first hand.
Storytime...
I had a buddy like that except it didn't go so well. MOST of the time he would hand guys twice his size their ass. UNFORTUNATELY, one night, he and I went to see a couple girls we knew up in farm country. And that night Kevin decided he was going to get drunk and...annoying. The problem is he annoyed a farm boy that was about four times his size.
After my then 6 foot 235 pound ass picked itself off the floor after farmer John threw me acroos the room for rudely interupting a heartfelt discussion between his foot and my friend's posterior, I decided to reassess my life choices a while and let my buddy enjoy the rather animated conversation.
As I didn't want ti interrupt his nap (he seemed rather tired after the animated heart to heart, I carried him to the truck and tucked him in. When I turned around, Farmer John wanted to, I thought, continue discussing world affairs with me. But fortunately he apologized for monopolizing the conversation earlier and we spent the night getting good and hammered ;)
