Frosty Returns Puns

Three strings walk into a bar. The first string goes up to the bartender and says,

"Hello, I'd like a pitcher of beer and three frosty glasses for me and my buddies, please."

The bartender replies,

"Sorry pal, but we don't serve strings here."

Dejected, the first string returns to his friends and relays the transaction. The second string can't believe this, and walks swiftly up to the bartender and says,

"Hey, buddy. I need a pitcher of beer and three frosty glasses for me and my friends!"

The bartender sternly states,

"We don't serve strings here!" The second string returns to his friends, defeated. The third string looks at his pals and says,

"Guys, I got this."

He goes into the bathroom, unravels himself a little and tangles himself up a bit. He walks confidently up to the bartender and says with gusto,

"Bartender! You are going to give me and my friends a pitcher of your finest beer, and three frosty glasses, on the double!"

The bartender sighs and says,

"Like I told your buddies, WE DON'T SERVE STRINGS HERE."

The third string leans across the bar, chuckles, and says,

"String? I'm a frayed knot."
