Phone Booth

Well, the texts below were extracted from the movie Phone Booth.
I don't understand "-Somebody got a 20 on this Pam?."(line 1157)
Anyone can help me out? Thanks alot in advance.



1146
00:28:33,130 --> 00:28:35,210
I keep him around because he
looks up to me.

1147
00:28:35,380 --> 00:28:39,630
Adam, if you' re watching, don't be
a publicist. You' re too good for it.

1148
00:28:39,800 --> 00:28:45,760
I lie in person and on the phone.
I lie to my friends.

1149
00:28:45,970 --> 00:28:50,130
I lie to newspapers and magazines who
sell my lies to more and more people.

1150
00:28:50,350 --> 00:28:55,640
I' m just a part of a big cycle of lies.
I should be *** president.

1151
00:28:55,900 --> 00:29:00,390
I wear all this ltalian *** because
underneath, I still feel like the Bronx.

1152
00:29:00,690 --> 00:29:03,230
I think I need these clothes,
and this watch.

1153
00:29:03,530 --> 00:29:08,190
My $2000 watch is a fake,
and so am l.

1154
00:29:08,580 --> 00:29:11,440
I neglected the things
I should've valued most.

1155
00:29:11,750 --> 00:29:13,490
I valued this ***.

1156
00:29:14,540 --> 00:29:20,830
I take off my wedding ring to call Pam.
Kelly, that's Pam.

1157
00:29:22,630 --> 00:29:24,870
-Somebody got a 20 on this Pam?.
-Don't blame her.

1158
00:29:25,130 --> 00:29:27,370
I never told her if I was married,
and if I did...

1159
00:29:27,630 --> 00:29:29,290
...she would've told me to go home.

1160
00:29:31,220 --> 00:29:35,550
Kelly, looking at you now,
l' m ashamed of myself.

1161
00:29:37,430 --> 00:29:43,300
I mean, I work so hard on this image,
on Stu Shepard, the ***...

1162
00:29:43,520 --> 00:29:48,430
...who refers to himself in third person,
that I only proved I should be alone.

1163
00:29:49,530 --> 00:29:53,300
I've been dressing up as something
l' m not for so long...

1164
00:29:53,570 --> 00:29:57,190
... I' m so afraid you won't like what's
underneath.

1165
00:29:57,410 --> 00:30:02,530
But here I am.
I' m just flesh and blood and weakness.

1166
00:30:05,040 --> 00:30:06,780
I love you so *** much.

1167
00:30:13,090 --> 00:30:18,540
I take off this ring because it only
reminds me of how I've failed you.

1168
00:30:18,800 --> 00:30:21,670
And, I don't wanna give you up.

1169
00:30:21,890 --> 00:30:25,960
I wanna make things better,
but it may not be my choice anymore.

1170
00:30:26,810 --> 00:30:29,340
You deserve better.

1171
00:30:44,780 --> 00:30:48,150
-You' re not gonna let me go.
-No.

1172
00:30:48,370 --> 00:30:52,140
You never were.
I know a thing about lies.

1173
00:30:52,370 --> 00:30:54,280
I know a thing or two
about liars as well.
